I am trying to enable the row based replication for mysql connection in clover by calling “SET SESSION binlog\_format = ‘ROW’;” in phase 0 of a graph.

I was thinking that different nodes using the same db connection will be using the same session of mysql, but apparently I was wrong.

My question is how I can enable clover to have the same mysql session for different db connection nodes in the same graph?

For example, I have two DBExecute nodes in my graph and I want them to have the same mysql session when being executed, rather than two different sessions.

Thanks in advance

Just set _threadSafeConnection_ attribute to false. Then all graph elements, that use the connection, use the same session (see [Database Connections](http://www.cloveretl.com/documentation/UserGuide/topic/com.cloveretl.gui.docs/docs/database-connections.html)).
