-------------------------------------------------------------
To query a specific replication task, run the changefeed query command. The query result includes the task information and the task state. You can specify the `--simple` or `-s` argument to simplify the query result that will only include the basic replication state and the checkpoint information. If you do not specify this argument, detailed task configuration, replication states, and replication table information are displayed.
