Removing replicated columns

You can alter replicated tables to remove columns from replication.

The replicates must be master replicates.

To remove one or more replicated columns from one or more replicates, run the cdr remaster command with the --remove option. You specify the database, table, and column names instead of the replicate names.

After you remove columns from replication, you can drop the columns.
