2017/11/20 - Amazon Kinesis - 1 new api methods

Changes  Customers can now obtain the important characteristics of their stream with DescribeStreamSummary. The response will not include the shard list for the stream but will have the number of open shards, and all the other fields included in the DescribeStream response.

DescribeStreamSummary (new) Link ΒΆ

Provides a summarized description of the specified Kinesis stream without the shard list.

The information returned includes the stream name, Amazon Resource Name (ARN), status, record retention period, approximate creation time, monitoring, encryption details, and open shard count.

Response Structure

  • (dict) --

    • StreamDescriptionSummary (dict) --

      A StreamDescriptionSummary containing information about the stream.

      • StreamName (string) --

        The name of the stream being described.

      • StreamARN (string) --

        The Amazon Resource Name (ARN) for the stream being described.

      • StreamStatus (string) --

        The current status of the stream being described. The stream status is one of the following states:

        • CREATING - The stream is being created. Kinesis Streams immediately returns and sets StreamStatus to CREATING .

        • DELETING - The stream is being deleted. The specified stream is in the DELETING state until Kinesis Streams completes the deletion.

        • ACTIVE - The stream exists and is ready for read and write operations or deletion. You should perform read and write operations only on an ACTIVE stream.

        • UPDATING - Shards in the stream are being merged or split. Read and write operations continue to work while the stream is in the UPDATING state.

      • RetentionPeriodHours (integer) --

        The current retention period, in hours.

      • StreamCreationTimestamp (datetime) --

        The approximate time that the stream was created.

      • EnhancedMonitoring (list) --

        Represents the current enhanced monitoring settings of the stream.

        • (dict) --

          Represents enhanced metrics types.

          • ShardLevelMetrics (list) --

            List of shard-level metrics.

            The following are the valid shard-level metrics. The value " ALL " enhances every metric.

            • IncomingBytes

            • IncomingRecords

            • OutgoingBytes

            • OutgoingRecords

            • WriteProvisionedThroughputExceeded

            • ReadProvisionedThroughputExceeded

            • IteratorAgeMilliseconds

            • ALL

            • (string) --

      • EncryptionType (string) --

        The encryption type used. This value is one of the following:

        • KMS

        • NONE

      • KeyId (string) --

        The GUID for the customer-managed KMS key to use for encryption. This value can be a globally unique identifier, a fully specified ARN to either an alias or a key, or an alias name prefixed by "alias/".You can also use a master key owned by Kinesis Streams by specifying the alias aws/kinesis .

        • Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012

        • Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

        • Globally unique key ID example: 12345678-1234-1234-1234-123456789012

        • Alias name example: alias/MyAliasName

        • Master key owned by Kinesis: alias/aws/kinesis

      • OpenShardCount (integer) --

        The number of open shards in the stream.
