Removing replicated columns

You can alter replicated tables to remove columns from replication.

Before you begin

The replicates must be master replicates.

About this task

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.

What to do next

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