FULL_NODUP mode for binlog_row_image

Details

    Description

      With FULL_NODUP mode, all columns are included in before image, but only updated columns are included in after image for UPDATE. While all columns are included in the after image for INSERT.

      FULL_NODUP is for replacing FULL mode. It includes all data of the before and after image as FULL mode, but it uses less storage, especially in the case that only a few columns are updated.

      This Jira is to track the contribution by Alibaba (https://github.com/MariaDB/server/pull/2803)

      (Note that originally the MDEV was referring to the original Alibaba option, FULL_DIFFERENT. This was changed to FULL_NODUP to reflect the option implemented in MariaDB).

            Note that with the final version this mode was called FULL_NODUP.
