Amazon DynamoDB

2019/11/12 - Amazon DynamoDB - 2 updated api methods

Changes  Amazon DynamoDB enables you to restore your data to a new DynamoDB table using a point-in-time or on-demand backup. You now can modify the settings on the new restored table. Specifically, you can exclude some or all of the local and global secondary indexes from being created with the restored table. In addition, you can change the billing mode and provisioned capacity settings.

Creates a new table from an existing backup. Any number of users can execute up to 4 concurrent restores (any type of restore) in a given account.

You can call RestoreTableFromBackup at a maximum rate of 10 times per second.

You must manually set up the following on the restored table:

  • Auto scaling policies

  • IAM policies

  • Amazon CloudWatch metrics and alarms

  • Tags

  • Stream settings

  • Time to Live (TTL) settings

type TargetTableName

string

param TargetTableName

[REQUIRED]

The name of the new table to which the backup must be restored.

type BackupArn

string

param BackupArn

[REQUIRED]

The Amazon Resource Name (ARN) associated with the backup.

type BillingModeOverride

string

param BillingModeOverride

The billing mode of the restored table.

type GlobalSecondaryIndexOverride

list

param GlobalSecondaryIndexOverride

List of global secondary indexes for the restored table. The indexes provided should match existing secondary indexes. You can choose to exclude some or all of the indexes at the time of restore.

  • (dict) --

    Represents the properties of a global secondary index.

    • IndexName (string) -- [REQUIRED]

      The name of the global secondary index. The name must be unique among all other indexes on this table.

    • KeySchema (list) -- [REQUIRED]

      The complete key schema for a global secondary index, which consists of one or more pairs of attribute names and key types:

      • HASH - partition key

      • RANGE - sort key

      Note

      The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

      The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

      • (dict) --

        Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

        A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

        A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

        • AttributeName (string) -- [REQUIRED]

          The name of a key attribute.

        • KeyType (string) -- [REQUIRED]

          The role that this key attribute will assume:

          • HASH - partition key

          • RANGE - sort key

          Note

          The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

          The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

    • Projection (dict) -- [REQUIRED]

      Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

      • ProjectionType (string) --

        The set of attributes that are projected into the index:

        • KEYS_ONLY - Only the index and primary keys are projected into the index.

        • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

        • ALL - All of the table attributes are projected into the index.

      • NonKeyAttributes (list) --

        Represents the non-key attribute names which will be projected into the index.

        For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

        • (string) --

    • ProvisionedThroughput (dict) --

      Represents the provisioned throughput settings for the specified global secondary index.

      For current minimum and maximum provisioned throughput values, see Limits in the Amazon DynamoDB Developer Guide .

      • ReadCapacityUnits (integer) -- [REQUIRED]

        The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .

        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.

      • WriteCapacityUnits (integer) -- [REQUIRED]

        The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .

        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.

type LocalSecondaryIndexOverride

list

param LocalSecondaryIndexOverride

List of local secondary indexes for the restored table. The indexes provided should match existing secondary indexes. You can choose to exclude some or all of the indexes at the time of restore.

  • (dict) --

    Represents the properties of a local secondary index.

    • IndexName (string) -- [REQUIRED]

      The name of the local secondary index. The name must be unique among all other indexes on this table.

    • KeySchema (list) -- [REQUIRED]

      The complete key schema for the local secondary index, consisting of one or more pairs of attribute names and key types:

      • HASH - partition key

      • RANGE - sort key

      Note

      The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

            • B - the attribute is of type Binary

      • TableName (string) --

        The name of the table.

      • KeySchema (list) --

        The primary key structure for the table. Each KeySchemaElement consists of:

        • AttributeName - The name of the attribute.

        • KeyType - The role of the attribute:

          • HASH - partition key

          • RANGE - sort key

        Note

        The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

        The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

        • NumberOfDecreasesToday (integer) --

          The number of provisioned throughput decreases for this table during this UTC calendar day. For current maximums on provisioned throughput decreases, see Limits in the Amazon DynamoDB Developer Guide .

        • ReadCapacityUnits (integer) --

          The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . Eventually consistent reads require less effort than strongly consistent reads, so a setting of 50 ReadCapacityUnits per second provides 100 eventually consistent ReadCapacityUnits per second.

        • WriteCapacityUnits (integer) --

          The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .

      • TableSizeBytes (integer) --

        The total size of the specified table, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

      • ItemCount (integer) --

        The number of items in the specified table. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

      • TableArn (string) --

        The Amazon Resource Name (ARN) that uniquely identifies the table.

      • TableId (string) --

        Unique identifier for the table for which the backup was created.

      • BillingModeSummary (dict) --

        Contains the details for the read/write capacity mode.

        • BillingMode (string) --

          Controls how you are charged for read and write throughput and how you manage capacity. This setting can be changed later.

          • PROVISIONED - Sets the read/write capacity mode to PROVISIONED . We recommend using PROVISIONED for predictable workloads.

          • PAY_PER_REQUEST - Sets the read/write capacity mode to PAY_PER_REQUEST . We recommend using PAY_PER_REQUEST for unpredictable workloads.

        • LastUpdateToPayPerRequestDateTime (datetime) --

          Represents the time when PAY_PER_REQUEST was last set as the read/write capacity mode.

      • LocalSecondaryIndexes (list) --

        Represents one or more local secondary indexes on the table. Each index is scoped to a given partition key value. Tables with one or more local secondary indexes are subject to an item collection size limit, where the amount of data within a given item collection cannot exceed 10 GB. Each element is composed of:

        • IndexName - The name of the local secondary index.

        • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.

        • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:

          • ProjectionType - One of the following:

            • KEYS_ONLY - Only the index and primary keys are projected into the index.

            • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

            • ALL - All of the table attributes are projected into the index.

          • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

        • IndexSizeBytes - Represents the total size of the index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • ItemCount - Represents the number of items in the index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        If the table is in the DELETING state, no information about indexes will be returned.

        • (dict) --

          Represents the properties of a local secondary index.

          • IndexName (string) --

            Represents the name of the local secondary index.

          • KeySchema (list) --

            The complete key schema for the local secondary index, consisting of one or more pairs of attribute names and key types:

            • HASH - partition key

            • RANGE - sort key

            Note

            The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

            The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

            • (dict) --

              Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

              A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

              A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

              • AttributeName (string) --

                The name of a key attribute.

              • KeyType (string) --

                • HASH - partition key

                • RANGE - sort key

                Note

                The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

                The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

          • Projection (dict) --

            Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

            • ProjectionType (string) --

              The set of attributes that are projected into the index:

              • KEYS_ONLY - Only the index and primary keys are projected into the index.

              • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

              • ALL - All of the table attributes are projected into the index.

            • NonKeyAttributes (list) --

              Represents the non-key attribute names which will be projected into the index.

              For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

              • (string) --

          • IndexSizeBytes (integer) --

            The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • ItemCount (integer) --

            The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • IndexArn (string) --

            The Amazon Resource Name (ARN) that uniquely identifies the index.

      • GlobalSecondaryIndexes (list) --

        The global secondary indexes, if any, on the table. Each index is scoped to a given partition key value. Each element is composed of:

        • Backfilling - If true, then the index is currently in the backfilling phase. Backfilling occurs only when a new global secondary index is added to the table. It is the process by which DynamoDB populates the new index with data from the table. (This attribute does not appear for indexes that were created during a CreateTable operation.) You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can't delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false. (This attribute does not appear for indexes that were created during a CreateTable operation.)

        • IndexName - The name of the global secondary index.

        • IndexSizeBytes - The total size of the global secondary index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • IndexStatus - The current status of the global secondary index:

          • CREATING - The index is being created.

          • UPDATING - The index is being updated.

          • DELETING - The index is being deleted.

          • ACTIVE - The index is ready for use.

        • ItemCount - The number of items in the global secondary index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.

        • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:

            • ALL - All of the table attributes are projected into the index.

          • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

        • ProvisionedThroughput - The provisioned throughput settings for the global secondary index, consisting of read and write capacity units, along with data about increases and decreases.

        If the table is in the DELETING state, no information about indexes will be returned.

            • ProjectionType (string) --

              The set of attributes that are projected into the index:

              • KEYS_ONLY - Only the index and primary keys are projected into the index.

              • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

              • ALL - All of the table attributes are projected into the index.

            • NonKeyAttributes (list) --

              Represents the non-key attribute names which will be projected into the index.

              For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

              • (string) --

          • IndexStatus (string) --

            The current state of the global secondary index:

            • UPDATING - The index is being updated.

            • DELETING - The index is being deleted.

            • ACTIVE - The index is ready for use.

          • Backfilling (boolean) --

            Indicates whether the index is currently backfilling. Backfilling is the process of reading items from the table and determining whether they can be added to the index. (Not all items will qualify: For example, a partition key cannot have any duplicate values.) If an item can be added to the index, DynamoDB will do so. After all items have been processed, the backfilling operation is complete and Backfilling is false.

            You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can't delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false.

            Note

            For indexes that were created during a CreateTable operation, the Backfilling attribute does not appear in the DescribeTable output.

            • NumberOfDecreasesToday (integer) --

              The number of provisioned throughput decreases for this table during this UTC calendar day. For current maximums on provisioned throughput decreases, see Limits in the Amazon DynamoDB Developer Guide .

            • ReadCapacityUnits (integer) --

              The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . Eventually consistent reads require less effort than strongly consistent reads, so a setting of 50 ReadCapacityUnits per second provides 100 eventually consistent ReadCapacityUnits per second.

            • WriteCapacityUnits (integer) --

              The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .

          • IndexSizeBytes (integer) --

            The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • ItemCount (integer) --

        • StreamViewType (string) --

          When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:

          • KEYS_ONLY - Only the key attributes of the modified item are written to the stream.

          • NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.

          • OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.

          • NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.

      • LatestStreamLabel (string) --

        A timestamp, in ISO 8601 format, for this stream.

        Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

Restores the specified table to the specified point in time within EarliestRestorableDateTime and LatestRestorableDateTime . You can restore your table to any point in time during the last 35 days. Any number of users can execute up to 4 concurrent restores (any type of restore) in a given account.

When you restore using point in time recovery, DynamoDB restores your table data to the state based on the selected date and time (day:hour:minute:second) to a new table.

Along with data, the following are also included on the new restored table using point in time recovery:

  • Global secondary indexes (GSIs)

  • Local secondary indexes (LSIs)

  • Provisioned read and write capacity

  • Encryption settings

Warning

All these settings come from the current settings of the source table at the time of restore.

You must manually set up the following on the restored table:

  • Auto scaling policies

  • IAM policies

  • Amazon CloudWatch metrics and alarms

  • Tags

  • Stream settings

  • Time to Live (TTL) settings

  • Point in time recovery settings

The billing mode of the restored table.

type GlobalSecondaryIndexOverride

list

param GlobalSecondaryIndexOverride

List of global secondary indexes for the restored table. The indexes provided should match existing secondary indexes. You can choose to exclude some or all of the indexes at the time of restore.

  • (dict) --

    Represents the properties of a global secondary index.

    • IndexName (string) -- [REQUIRED]

      The name of the global secondary index. The name must be unique among all other indexes on this table.

    • KeySchema (list) -- [REQUIRED]

      The complete key schema for a global secondary index, which consists of one or more pairs of attribute names and key types:

      • HASH - partition key

      • RANGE - sort key

      Note

      The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

      The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

      • (dict) --

        Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

        A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

        A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

        • AttributeName (string) -- [REQUIRED]

          The name of a key attribute.

        • KeyType (string) -- [REQUIRED]

          The role that this key attribute will assume:

          • HASH - partition key

          • RANGE - sort key

    • Projection (dict) -- [REQUIRED]

      Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

      • ProjectionType (string) --

        The set of attributes that are projected into the index:

        • KEYS_ONLY - Only the index and primary keys are projected into the index.

        • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

        • ALL - All of the table attributes are projected into the index.

      • NonKeyAttributes (list) --

        Represents the non-key attribute names which will be projected into the index.

        For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

        • (string) --

        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.

      • WriteCapacityUnits (integer) -- [REQUIRED]

        The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .

        If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.

                Note

                The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

                The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

          • Projection (dict) --

            Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

            • ProjectionType (string) --

              The set of attributes that are projected into the index:

              • KEYS_ONLY - Only the index and primary keys are projected into the index.

              • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

              • ALL - All of the table attributes are projected into the index.

            • NonKeyAttributes (list) --

              Represents the non-key attribute names which will be projected into the index.

              For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

              • (string) --

          • IndexSizeBytes (integer) --

            The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • ItemCount (integer) --

            The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • IndexArn (string) --

            The Amazon Resource Name (ARN) that uniquely identifies the index.

      • GlobalSecondaryIndexes (list) --

        The global secondary indexes, if any, on the table. Each index is scoped to a given partition key value. Each element is composed of:

        • Backfilling - If true, then the index is currently in the backfilling phase. Backfilling occurs only when a new global secondary index is added to the table. It is the process by which DynamoDB populates the new index with data from the table. (This attribute does not appear for indexes that were created during a CreateTable operation.) You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can't delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false. (This attribute does not appear for indexes that were created during a CreateTable operation.)

        • IndexName - The name of the global secondary index.

        • IndexSizeBytes - The total size of the global secondary index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • IndexStatus - The current status of the global secondary index:

          • CREATING - The index is being created.

          • UPDATING - The index is being updated.

          • DELETING - The index is being deleted.

          • ACTIVE - The index is ready for use.

        • ItemCount - The number of items in the global secondary index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.

        • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:

          • ProjectionType - One of the following:

            • KEYS_ONLY - Only the index and primary keys are projected into the index.

            • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

            • ALL - All of the table attributes are projected into the index.

          • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

        • ProvisionedThroughput - The provisioned throughput settings for the global secondary index, consisting of read and write capacity units, along with data about increases and decreases.

        If the table is in the DELETING state, no information about indexes will be returned.

        • (dict) --

          Represents the properties of a global secondary index.

          • IndexName (string) --

            The name of the global secondary index.

          • KeySchema (list) --

            The complete key schema for a global secondary index, which consists of one or more pairs of attribute names and key types:

            • HASH - partition key

            • RANGE - sort key

            Note

            The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

            The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

            • (dict) --

              Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

              A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

              A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

              • AttributeName (string) --

                The name of a key attribute.

              • KeyType (string) --

                The role that this key attribute will assume:

                • HASH - partition key

                • RANGE - sort key

                Note

                The partition key of an item is also known as its hash attribute . The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

                The sort key of an item is also known as its range attribute . The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

          • Projection (dict) --

            Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

            • ProjectionType (string) --

              The set of attributes that are projected into the index:

              • KEYS_ONLY - Only the index and primary keys are projected into the index.

              • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .

              • ALL - All of the table attributes are projected into the index.

            • NonKeyAttributes (list) --

              Represents the non-key attribute names which will be projected into the index.

              For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

              • (string) --

          • IndexStatus (string) --

            The current state of the global secondary index:

            • CREATING - The index is being created.

            • UPDATING - The index is being updated.

            • DELETING - The index is being deleted.

            • ACTIVE - The index is ready for use.

          • Backfilling (boolean) --

            Indicates whether the index is currently backfilling. Backfilling is the process of reading items from the table and determining whether they can be added to the index. (Not all items will qualify: For example, a partition key cannot have any duplicate values.) If an item can be added to the index, DynamoDB will do so. After all items have been processed, the backfilling operation is complete and Backfilling is false.

            You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can't delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false.

            Note

            For indexes that were created during a CreateTable operation, the Backfilling attribute does not appear in the DescribeTable output.

          • ProvisionedThroughput (dict) --

            Represents the provisioned throughput settings for the specified global secondary index.

            For current minimum and maximum provisioned throughput values, see Limits in the Amazon DynamoDB Developer Guide .

            • LastIncreaseDateTime (datetime) --

              The date and time of the last provisioned throughput increase for this table.

            • LastDecreaseDateTime (datetime) --

              The date and time of the last provisioned throughput decrease for this table.

            • NumberOfDecreasesToday (integer) --

              The number of provisioned throughput decreases for this table during this UTC calendar day. For current maximums on provisioned throughput decreases, see Limits in the Amazon DynamoDB Developer Guide .

            • ReadCapacityUnits (integer) --

              The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . Eventually consistent reads require less effort than strongly consistent reads, so a setting of 50 ReadCapacityUnits per second provides 100 eventually consistent ReadCapacityUnits per second.

            • WriteCapacityUnits (integer) --

              The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .

          • IndexSizeBytes (integer) --

            The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

          • ItemCount (integer) --

            The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

            The Amazon Resource Name (ARN) that uniquely identifies the index.

      • StreamSpecification (dict) --

        The current DynamoDB Streams configuration for the table.

        • StreamEnabled (boolean) --

          Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.

        • StreamViewType (string) --

          When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:

          • KEYS_ONLY - Only the key attributes of the modified item are written to the stream.

          • NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.

          • OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.

          • NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.

      • LatestStreamLabel (string) --

        A timestamp, in ISO 8601 format, for this stream.

        Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

        • AWS customer ID

        • Table name

        • StreamLabel

      • LatestStreamArn (string) --

        The Amazon Resource Name (ARN) that uniquely identifies the latest stream for this table.

          Indicates if a restore is in progress or not.

      • SSEDescription (dict) --

        The description of the server-side encryption status on the specified table.

        • Status (string) --

          Represents the current state of server-side encryption. The only supported values are:

          • ENABLED - Server-side encryption is enabled.

          • UPDATING - Server-side encryption is being updated.

        • SSEType (string) --

          Server-side encryption type. The only supported value is:

          • KMS - Server-side encryption that uses AWS Key Management Service. The key is stored in your account and is managed by AWS KMS (AWS KMS charges apply).

        • KMSMasterKeyArn (string) --

          The KMS customer master key (CMK) ARN used for the AWS KMS encryption.
