Re: Multiple masters to single slave

The main configurations practical:

* One Master with many Slaves. ("Star")

* Two Masters (dual-master) each replicating from each other, and each (optionally) having any number of Slaves. This is the best choice for HA. However, to avoid numerous problems, only one Master is writable at any given time.

* "Relay". Add to either of the above slaves hanging off one of the slaves. (Caution: The relay is a 'single-point-of-failure'.)

Back to the original question, plus expanding on Lee's suggestion:

Don't solve the problem with replication, instead use Federation. That is, your 'report' machine (optionally one of the existing ones) reads 'Federated' tables, which are really the live tables on the various Masters.
