> * Introduce a METADATAONLY option as part of the REPL DUMP command which will
> only try and dump out events for DDL changes, this will be faster as we wont
> need scan of files on HDFS for DML changes.
> * Additionally since we are only going to dump metadata operations, it might
> be useful to include acid tables as well via an option as well. This option
> can be removed when ACID support is complete via HIVE-18320
> it will be good to support the "WITH" clause as part of REPL DUMP command as
> well (repl dump already supports it viaHIVE-17757) to achieve the above as
> that will prevent less changes to the syntax of the statement and provide
> more flexibility in future to include additional options as well.
> {code}
> REPL DUMP [db_name] {FROM [event_id]} {TO [event_id]} {WITH
> (['key'='value'],.....)}
> {code}
> This will enable other tools like security / schema registry / metadata
> discovery to use replication related subsystem for their needs as well.
