New to RDS (used to having my own server in my own data center).
We are on MySQL 5.6 on RDS.
when a slave gets behind in replication lag, the master ceases to rotate out its binary logs. It is, apparently, waiting to every slave to commit every transaction before rotating binary logs out. I don't have a problem with this conceptually (as long as you have monitors on disk space on the master, its a good thing).
My question is academic -- what causes this to happen?
** I know with ASYNCHRONOUS replication, the master is unaware of the slaves' status
is this a function of synchronous replication? semi-synchronous replication?
I'd love some insight and perhaps a pointer to a white paper somewhere (I can not find one that addresses this specific issue of binary logs not being rotated out)
