Replication Options
===================

The metadata file is a way to share information between mydumper and myloader.

There are 3 options on the metadata file to control which replication commands will execute myloader.

The option is :option:`--source-data <mydumper --source-data>`, which accepts a value between -1 and 7 following this table:
