Re: Error 1112 on Innodb to ndb replication

Hi,
Is there anything interesting in the MySQLD error log on the Slave MySQLD?

One difference with replication using MySQL Cluster is that we do not currently support multi-source replication, or the use of the multi-threaded-slave.

If those features are configured then the Slave may stop with error 1112.

MySQL Cluster replication requires that a MySQLD acting as a Slave has 1 incoming replication channel, and uses a single SQL applier thread.

Apart from the above, error 1112 is generated only during DDL statements, and is probably unlikely to be seen.

Hope this helps,
Frazer
