For information on the attributes available for connecting your source or target endpoint, see Working with AWS DMS Endpoints in the AWS Database Migration Service User Guide.
string
An AWS KMS key identifier that is used to encrypt the connection parameters for the endpoint.
If you don't specify a value for the KmsKeyId parameter, then AWS DMS uses your default encryption key.
AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.
list
One or more tags to be assigned to the endpoint.
(dict) --
Key (string) --
A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and cannot be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
Value (string) --
A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and cannot be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
string
The Amazon Resource Name (ARN) for the certificate.
string
The Secure Sockets Layer (SSL) mode to use for the SSL connection. The default is none
string
The Amazon Resource Name (ARN) for the service access role that you want to use to create the endpoint.
string
The external table definition.
dict
Settings in JSON format for the target Amazon DynamoDB endpoint. For more information about the available settings, see Using Object Mapping to Migrate Data to DynamoDB in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) -- [REQUIRED]
The Amazon Resource Name (ARN) used by the service access IAM role.
dict
Settings in JSON format for the target Amazon S3 endpoint. For more information about the available settings, see Extra Connection Attributes When Using Amazon S3 as a Target for AWS DMS in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) used by the service access IAM role.
ExternalTableDefinition (string) --
The external table definition.
CsvRowDelimiter (string) --
The delimiter used to separate rows in the source files. The default is a carriage return ( \n).
CsvDelimiter (string) --
The delimiter used to separate columns in the source files. The default is a comma.
BucketFolder (string) --
An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path bucketFolder/schema_name/table_name/. If this parameter is not specified, then the path used is schema_name/table_name/.
BucketName (string) --
The name of the S3 bucket.
CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Set to NONE (the default) or do not use to leave the files uncompressed. Applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. To use SSE_S3, you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode, provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=value,BucketFolder=value,BucketName=value,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=value
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0.
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.

An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Set to NONE (the default) or do not use to leave the files uncompressed. Applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. To use SSE_S3, you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode, provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=value,BucketFolder=value,BucketName=value,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=value
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0.
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.

DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0.
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
DmsTransferSettings (dict) --
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string
JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. To use SSE_S3, you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode, provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=value,BucketFolder=value,BucketName=value,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=value
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0.
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
DmsTransferSettings (dict) --
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string
JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

dict
Settings in JSON format for the target Amazon S3 endpoint. For more information about the available settings, see Extra Connection Attributes When Using Amazon S3 as a Target for AWS DMS in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) used by the service access IAM role.
ExternalTableDefinition (string) --
The external table definition.
CsvRowDelimiter (string) --
The delimiter used to separate rows in the source files. The default is a carriage return ( \n).
CsvDelimiter (string) --
The delimiter used to separate columns in the source files. The default is a comma.
BucketFolder (string) --
An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path bucketFolder/schema_name/table_name/. If this parameter is not specified, then the path used is schema_name/table_name/.
BucketName (string) --

CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Set to NONE (the default) or do not use to leave the files uncompressed. Applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. To use SSE_S3, you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode, provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=value,BucketFolder=value,BucketName=value,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=value
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0.
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.

For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide..
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName.
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
When ParquetTimestampInMillisecond is set to true or y, AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
DmsTransferSettings (dict) --
