ModifyDtsJobEndpoint - Data Transmission Service - Alibaba Cloud Documentation Center

Note After the database is changed, DTS rolls back the incremental write offset for 10 seconds. If the synchronized or migrated data does not have a primary key, make sure that no data is written to the source database while the source or destination database is being replaced. Otherwise, duplicate data may exist.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Note This parameter is valid and required only if the source database is an ApsaraDB for MongoDB sharded cluster instance. This parameter is valid only if ModifyAccount is set to true.
RoleName	String	No	ram-for-dts	The name of the Resource Access Management (RAM) role that you specify to access resources across Alibaba Cloud accounts. Note This parameter is required if you synchronize or migrate data across Alibaba Cloud accounts. For more information, see Configure RAM authorization for cross-account DTS tasks.
AliyunUid	String	No	150780020300****	The ID of the Alibaba Cloud account to which the database instance belongs. Note If you specify this parameter, data is synchronized or migrated across Alibaba Cloud accounts. You must also specify RoleName.
DryRun	Boolean	No	true	Specifies whether to perform only a precheck. Valid values: true: Yes. After the precheck is passed, the database is not changed. false (default): No. After the precheck is passed, the database is changed and the DTS task is run.
