Querying Details About Tasks Created Asynchronously in Batches with a Specified ID

Function

This API is used to query details about the tasks created asynchronously in batches with a specified ID. By default, the return results are sorted by create_time in descending order. Pagination query is supported.

Constraints

This API is available only for synchronization from MySQL to MySQL, migration from Redis to GeminiDB Redis, migration from Redis Cluster to GeminiDB Redis, and synchronization from Oracle to GaussDB Distributed.
This API can be used only in certain regions. For details, see Endpoints.

conflict_policy	String	Incremental conflict policy. The conflict policy refers to the conflict handling policy during incremental synchronization. By default, conflicts in the full synchronization phase are ignored. Values: ignore: Ignore the conflict. The system will ignore the conflicting data and continue the subsequent synchronization process. stop: Report an error. The synchronization task will be stopped and fail. You can view the details in synchronization logs. overwrite: Overwrite the existing data with the synchronized data. Conflicting data will be overwritten. Scenarios: Real-time migration: Not supported. Real-time synchronization: Supported. Enumerated values: ignore stop overwrite
index_trans	Boolean	Object synchronization scope: indicates whether to synchronize normal indexes. By default, DRS synchronizes the primary key or unique index. A normal index refers to an index other than the primary key or unique index. Values: true: All indexes will be synchronized. false: Only primary key or unique indexes are synchronized. Default value: true

DROP_INDEX: Delete an index. ADD_INDEX: Add an index. CREATE_INDEX: Create an index. RENAME_INDEX: Rename an index. Note: In one-to-one and one-to-many scenarios, if the DDL usage of the source and destination databases must be consistent, high-risk DDLs must be synchronized. In one-to-one and one-to-many scenarios, if you do not want a high-risk DDL to be performed in the destination, deselect the high-risk DDL to protect destination data. However, filtering DDL may cause synchronization to fail, for example, column deletion. In many-to-one data synchronization tasks, it is recommended that only the ADD COLUMN operation is synchronized, or tasks may fail or data may be inconsistent due to changes in destination tables. Typical failure scenarios are as follows: Synchronizing the TRUNCATE operation clears all destination data. Synchronizing the CREATE INDEX operation locks the destination table. Synchronizing the RENAME operation causes other task failure because the destination table cannot be found. Synchronizing the MODIFY COLUMN operation causes other task failure due to incompatible data types. Enumerated values: CREATE_TABLE ADD_COLUMN MODIFY_COLUMN CHANGE_COLUMN DROP_INDEX ADD_INDEX CREATE_INDEX RENAME_INDEX
sync_type_policy	String	Synchronization object type. Values: supportAllType: All types. tableData: Data. tableStructure: Table structure. constraintData: Index. NOTE: Except supportAllType, other types can be specified together, for example, tableData,tableStructure.
