    Check Details

    • Check requirements: in a MongoDB migration task, if the source database is a sharded database, you need to enter the mongos, config server, and mongod node information.
    • Check description: the information of the mongos, config server, and mongod nodes cannot be disordered; otherwise, data migration will also be disordered; for example, the mongos node information should not be entered in the box for the mongod node. Note that you only need to enter the information of one mongod node for each shard.


    • Enter the correct node information in the DTS task configuration items.
    • Enter only one mongod for each shard.
