Hi,

Consider the following scenario:
You have a replicated environment, let's say a MMR setup. Now, one of the masters (M2) is down for a period of time and updates were performed against the other master (M1). How long does it take until both boxes are in sync, after M2 is back online. I assume that M1 tries to update M2 throughout the downtime in an interval setting. If this is right, what is this interval and secondly, can this be configured.

The interval uses a backoff strategy - it first tries after 1 second, then after 2 seconds, then after 4 seconds, etc. doubling every time until it hits a maximum of every 5 minutes. This is not configurable, but there is a way to send updates now which will break it out of the wait/backoff.

Thanks,
-Reinhard
