Calls to functions are logged directly on the Binary Log. Therefore if you don't have all functions created on all your servers you will break your replication and the SQL process will stop with an error.

Example:

mysql> CREATE FUNCTION this year() RETURNS INT DETERMINISTIC RETURN YEAR(CURDATE());

mysql> insert into t VALUES(this_year());

Binary Log:

# 111213 23:25:46 server id 1 end_log_pos 676 Query thread_id=5 exec_time=0 error_code=0

SET TIMESTAMP=1323815146…

Binary Log Management

Coupled with the changes to replica binary logging we will be releasing several updates to our tool that manages binary logs. This tool will be receiving updates to enable it to purge binary logs on replica databases. Along with this change we will also be adding a bunch of other features:

Quicker Initial Purge: Initial log removal (when master-bin.000001 exists) will now happen at 50% disk usage by default instead of 90%. This will reduce concerns about disk space …
