Properties

AcceptAnyDate

A value that indicates to allow any date format, including invalid formats such as 00/00/00 00:00:00, to be loaded without generating an error. You can choose true or false (the default).

This parameter applies only to TIMESTAMP and DATE columns. Always use ACCEPTANYDATE with the DATEFORMAT parameter. If the date format for the data doesn't match the DATEFORMAT specification, Amazon Redshift inserts a NULL value into that field.

Required: No

Type: Boolean

Update requires: No interruption

AfterConnectScript

Code to run after connecting. This parameter should contain the code itself, not the name of a file containing the code.

Required: No

Type: String

Update requires: No interruption

BucketFolder

An S3 folder where the comma-separated-value (.csv) files are stored before being uploaded to the target Redshift cluster.

For full load mode, AWS DMS converts source records into .csv files and loads them to the BucketFolder/TableID path. AWS DMS uses the Redshift COPY command to upload the .csv files to the target table. The files are deleted once the COPY operation has finished. For more information, see COPY in the Amazon Redshift Database Developer Guide.

For change-data-capture (CDC) mode, AWS DMS creates a NetChanges table, and loads the .csv files to this BucketFolder/NetChangesTableID path.

Required: No

Type: String

Update requires: No interruption

BucketName

The name of the intermediate S3 bucket used to store .csv files before uploading data to Redshift.

Required: No

Type: String

Update requires: No interruption

CaseSensitiveNames

If Amazon Redshift is configured to support case sensitive schema names, set CaseSensitiveNames to true. The default is false.

Required: No

Type: Boolean

Update requires: No interruption

CompUpdate

If you set CompUpdate to true Amazon Redshift applies automatic compression if the table is empty. This applies even if the table columns already have encodings other than RAW. If you set CompUpdate to false, automatic compression is disabled and existing column encodings aren't changed. The default is true.

Required: No

Type: Boolean

Update requires: No interruption

ConnectionTimeout

A value that sets the amount of time to wait (in milliseconds) before timing out, beginning from when you initially establish a connection.

Required: No

Type: Integer

Update requires: No interruption

DateFormat

The date format that you are using. Valid values are auto (case-sensitive), your date format string enclosed in quotes, or NULL. If this parameter is left unset (NULL), it defaults to a format of 'YYYY-MM-DD'. Using auto recognizes most strings, even some that aren't supported when you use a date format string.

If your date and time values use formats different from each other, set this to auto.

Required: No

Type: String

Update requires: No interruption

EmptyAsNull

A value that specifies whether AWS DMS should migrate empty CHAR and VARCHAR fields as NULL. A value of true sets empty CHAR and VARCHAR fields to null. The default is false.

Required: No

Type: Boolean

Update requires: No interruption

EncryptionMode

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.

Note

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, create an AWS Identity and Access Management (IAM) role with a policy that allows "arn:aws:s3:::*" to use the following actions: "s3:PutObject", "s3:ListBucket"

Required: No

Type: String

Allowed values: sse-s3 | sse-kms

Update requires: No interruption

ExplicitIds

This setting is only valid for a full-load migration task. Set ExplicitIds to true to have tables with IDENTITY columns override their auto-generated values with explicit values loaded from the source data files used to populate the tables. The default is false.

Required: No

Type: Boolean

Update requires: No interruption

FileTransferUploadStreams

The number of threads used to upload a single file. This parameter accepts a value from 1 through 64. It defaults to 10.

The number of parallel streams used to upload a single .csv file to an S3 bucket using S3 Multipart Upload. For more information, see Multipart upload overview.

FileTransferUploadStreams accepts a value from 1 through 64. It defaults to 10.

Required: No

Type: Integer

Update requires: No interruption

LoadTimeout

The amount of time to wait (in milliseconds) before timing out of operations performed by AWS DMS on a Redshift cluster, such as Redshift COPY, INSERT, DELETE, and UPDATE.

Required: No

Type: Integer

Update requires: No interruption

MapBooleanAsBoolean

When true, lets Redshift migrate the boolean type as boolean. By default, Redshift migrates booleans as varchar(1). You must set this setting on both the source and target endpoints for it to take effect.

Required: No

Type: Boolean

Update requires: No interruption

MaxFileSize

The maximum size (in KB) of any .csv file used to load data on an S3 bucket and transfer data to Amazon Redshift. It defaults to 1048576KB (1 GB).

Required: No

Type: Integer

Update requires: No interruption

RemoveQuotes

A value that specifies to remove surrounding quotation marks from strings in the incoming data. All characters within the quotation marks, including delimiters, are retained. Choose true to remove quotation marks. The default is false.

Required: No

Type: Boolean

Update requires: No interruption

ReplaceChars

A value that specifies to replaces the invalid characters specified in ReplaceInvalidChars, substituting the specified characters instead. The default is "?".

Required: No

Type: String

Update requires: No interruption

ReplaceInvalidChars

A list of characters that you want to replace. Use with ReplaceChars.

Required: No

Type: String

Update requires: No interruption

SecretsManagerAccessRoleArn

The full Amazon Resource Name (ARN) of the IAM role that specifies AWS DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the AWS Secrets Manager secret that allows access to the Amazon Redshift endpoint.

Note

You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both.

For more information on creating this SecretsManagerSecret, the corresponding SecretsManagerAccessRoleArn, and the SecretsManagerSecretId that is required to access it, see Using secrets to access AWS Database Migration Service resources in the AWS Database Migration Service User Guide.

Required: No

Type: String

Update requires: No interruption

SecretsManagerSecretId

The full ARN, partial ARN, or display name of the SecretsManagerSecret that contains the Amazon Redshift endpoint connection details.

Required: No

Type: String

Update requires: No interruption

ServerSideEncryptionKmsKeyId

The AWS KMS key ID. If you are using SSE_KMS for the EncryptionMode, provide this key ID. The key that you use needs an attached policy that enables IAM user permissions and allows use of the key.

Required: No

Type: String

Update requires: No interruption

ServiceAccessRoleArn

The Amazon Resource Name (ARN) of the IAM role that has access to the Amazon Redshift service. The role must allow the iam:PassRole action.

Required: No

Type: String

Update requires: No interruption

TimeFormat

The time format that you want to use. Valid values are auto (case-sensitive), 'timeformat_string', 'epochsecs', or 'epochmillisecs'. It defaults to 10. Using auto recognizes most strings, even some that aren't supported when you use a time format string.

If your date and time values use formats different from each other, set this parameter to auto.

Required: No

Required: No

Type: Boolean

Update requires: No interruption

TruncateColumns

A value that specifies to truncate data in columns to the appropriate number of characters, so that the data fits in the column. This parameter applies only to columns with a VARCHAR or CHAR data type, and rows with a size of 4 MB or less. Choose true to truncate data. The default is false.

Required: No

Type: Boolean

Update requires: No interruption

WriteBufferSize

The size (in KB) of the in-memory file write buffer used when generating .csv files on the local disk at the DMS replication instance. The default value is 1000 (buffer size is 1000KB).

Required: No

Type: Integer
