Re: Example of Cluster SLOWER than InnoDB -- help?
I went and learned about mysql_set_server_option(MYSQL_OPTION_MULTI_STATEMENTS_ON) and mysql_next_result(). I think this saves a little back-and-forth latency.
I got rid of the dirty flag and restructured the transactions to get the same result from fewer statements.
I'm happy to report that I am now getting 96 messages sent and received (full contention-- that is, writer and reader looping as fast as possible) per second with Cluster vs. 147 with InnoDB. I was hoping that Cluster would do better than InnoDB and I think it will in a finished system with thousands of queue readers/writers and a multi-node cluster.
Does anyone have any thoughts on how this will scale? Will the inter-node locking negotiations slow it way down?
