§Properties

AfterConnectScript?: string | null

[src]

For use with change data capture (CDC) only, this attribute has DMS bypass foreign keys and user triggers to reduce the time it takes to bulk load data.

Example: afterConnectScript=SET session_replication_role='replica'

CaptureDdls?: boolean | null

[src]

To capture DDL events, DMS creates various artifacts in the PostgreSQL database when the task starts. You can later remove these artifacts.

If this value is set to N, you don't have to create tables or triggers on the source database.

DatabaseName?: string | null

[src]

Database name for the endpoint.

DdlArtifactsSchema?: string | null

[src]

The schema in which the operational DDL database artifacts are created.

Example: ddlArtifactsSchema=xyzddlschema;

ExecuteTimeout?: number | null

[src]

Sets the client statement timeout for the PostgreSQL instance, in seconds. The default value is 60 seconds.

Example: executeTimeout=100;

FailTasksOnLobTruncation?: boolean | null

[src]

When set to true, this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize.

If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

HeartbeatEnable?: boolean | null

[src]

The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios.

HeartbeatFrequency?: number | null

[src]

Sets the WAL heartbeat frequency (in minutes).

HeartbeatSchema?: string | null

[src]

Sets the schema in which the heartbeat artifacts are created.

MaxFileSize?: number | null

[src]

Specifies the maximum size (in KB) of any .csv file used to transfer data to PostgreSQL.

Example: maxFileSize=512

Password?: string | null

[src]

Endpoint connection password.

PluginName?: PluginNameValue | null

[src]

Specifies the plugin to use to create a replication slot.

Port?: number | null

[src]

Endpoint TCP port. The default is 5432.

SecretsManagerAccessRoleArn?: string | null

[src]

The full Amazon Resource Name (ARN) of the IAM role that specifies 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 Amazon Web Services Secrets Manager secret that allows access to the PostgreSQL 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 and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide.

SecretsManagerSecretId?: string | null

[src]

The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the PostgreSQL endpoint connection details.

ServerName?: string | null

[src]

Fully qualified domain name of the endpoint.

SlotName?: string | null

[src]

Sets the name of a previously created logical replication slot for a change data capture (CDC) load of the PostgreSQL source instance.

When used with the CdcStartPosition request parameter for the DMS API , this attribute also makes it possible to use native CDC start points. DMS verifies that the specified logical replication slot exists before starting the CDC load task. It also verifies that the task was created with a valid setting of CdcStartPosition. If the specified slot doesn't exist or the task doesn't have a valid CdcStartPosition setting, DMS raises an error.

For more information about setting the CdcStartPosition request parameter, see Determining a CDC native start point in the Database Migration Service User Guide. For more information about using CdcStartPosition, see CreateReplicationTask, StartReplicationTask, and ModifyReplicationTask.

Username?: string | null

[src]

Endpoint connection user name.
