I’ll be presenting a webinar next Wednesday, January 23 at 10 a.m. (Pacific Time), about issues application developers should think about for scaling out read-query traffic using multiple MySQL instances in a replication pair.

Specifically, about the care we have to take because replication is asynchronous.  This means the slave  may not have current data at all times, so an application must choose to query the slave or the master dynamically.  As much as possible, we’d like to automate this choice so that application developers can be the most productive.
