Re: Slaving from Mirror Mode Masters

Mirrormode - active/passive fail over. Only writes and other various meta properties will get to the active master.

The other node is a failover - ideally you shouldn't be making any writes to it that would normally go to the primary.

As for load, etc, the site I manage has a pretty small directory, so I can't offer any useful data.

Subject: Slaving from Mirror Mode Masters

Dear Folks,

We are setting up mirror mode masters with eight fairly heavily
loaded slaves (consumers).

Should they all slave from both masters?

An alternative is to slave from one, where a floating IP address is
that of "the master".

Please can anyone share their experience?

Would all slaves being consumers to two masters result in any marked
increased load on any of the servers?
