It sounds as if we'll get a chance to think together about how to help Tungsten Replicator implement similar callbacks from slaves so it can play nice with MySQL 5.5.Robert Hodgeshttps://www.blogger.com/profile/05379726998057344092noreply@blogger.comtag:blogger.com,1999:blog-16959946.post-41325268181743212122010-11-10T12:23:44.303+01:002010-11-10T12:23:44.303+01:00Very interesting post, lots of good information. i...Very interesting post, lots of good information. it's very helpful for me.

I have had at least one user who wanted to know when their commits reached a slave and they weren't thrilled about having to query slave status after each commit. Semi-sync will make life easier for them.<br /><br />Another benefit from semi-sync is that it rate limits busy users. When one connection tries to do a burst of transactions this can be used to make the client run only as fast as the throughput between the master and IO thread on the slave. That is useful for some deployments.Mark Callaghanhttps://www.blogger.com/profile/09590445221922043181noreply@blogger.com
