AWS DMS Task failed with error: Error executing source loop; Stream component failed at subtask 0

Question

I want to migrate my PostgresDB hosted in Citus cloud service to AWS RDS Aurora Postgres. I am using AWS DMS service. Have created task but getting following errors:

Last failure message Last Error Stream Component Fatal error. Task error notification received from subtask 0, thread 0 [reptask/replicationtask.c:2860] [1020101] Error executing source loop; Stream component failed at subtask 0, component st_0_QOIS7XIGJDKNPY6RXMGYRLJQHY2P7IQBWIBA5NQ; Stream component 'st_0_QOIS7XIGJDKNPY6RXMGYRLJQHY2P7IQBWIBA5NQ' terminated [reptask/replicationtask.c:2868] [1020101] Stop Reason FATAL_ERROR Error Level FATAL

Frankly speaking not able to understand what is wrong here, so any help is appreciated.

Answer 1

我将类型更改为完全加载它可以工作，因此它不适用于正在进行的复制 Citus Cloud 服务不支持它。

Answer 2

I had a similar error to this using Aurora PostgreSQL v14.5 and AWS DMS. I was using a DMS Full load + CDC job (using pglogical behind the scenes) to migrate from one table to another (on the same system).

Issue was resolved by rolling back my PostgreSQL version from 14.5 to 13.7.
