#cdc_inserts_and_updatesBoolean

A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false, but when CdcInsertsAndUpdates is set to true or y, only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false, CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide..

DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

Returns:

  • (Boolean)

#cdc_inserts_onlyBoolean

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 Database Migration Service User Guide..

DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

Returns:

  • (Boolean)

#cdc_pathString

Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set PreserveTransactions to true, DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by BucketFolder and BucketName .

For example, if you specify CdcPath as MyChangedData, and you specify BucketName as MyTargetBucket but do not specify BucketFolder, DMS creates the CDC folder path following: MyTargetBucket/MyChangedData.

If you specify the same CdcPath, and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData, DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData.

For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target.

This setting is supported in DMS versions 3.4.2 and later.

Returns:

  • (String)

#csv_no_sup_valueString

This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If UseCsvNoSupValue is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

This setting is supported in DMS versions 3.4.1 and later.

#csv_null_valueString

An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are not nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL.

The default value is NULL. Valid values include any valid string.

Returns:

  • (String)

#encoding_typeString

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.

Returns:

#encryption_modeString

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.

For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3. But you can’t change the existing value from SSE_S3 to SSE_KMS.

To use SSE_S3, you need an 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

Returns:

  • (String)

#include_op_for_full_loadBoolean

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.

DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

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.

This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide..

Returns:

  • (Boolean)

#parquet_timestamp_in_millisecondBoolean

A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

When ParquetTimestampInMillisecond is set to true or y, DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

Currently, Amazon Athena and 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 Glue.

DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

Returns:

  • (Boolean)

#rfc_4180Boolean

For an S3 source, when this value is set to true or y, each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n, string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value.

For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice.

The default value is true. Valid values include true, false, y, and n.

Returns:

  • (Boolean)

#timestamp_column_nameString

A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

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.

Returns:

  • (String)

#use_csv_no_sup_valueBoolean

This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by CsvNoSupValue . If not set or set to false, DMS uses the null value for these columns.

This setting is supported in DMS versions 3.4.1 and later.

Returns:

  • (Boolean)

#use_task_start_time_for_full_load_timestampBoolean

When set to true, this parameter uses the task start time as the timestamp column value instead of the time data is written to target. For full load, when useTaskStartTimeForFullLoadTimestamp is set to true, each row of the timestamp column contains the task start time. For CDC loads, each row of the timestamp column contains the transaction commit time.

When useTaskStartTimeForFullLoadTimestamp is set to false, the full load timestamp in the timestamp column increments with the time data arrives at the target.

Returns:

  • (Boolean)
