The issue about the special scenario in redis-2.2.12 about redis

[GoogleCodeExporter]

Each server is a slave of the other? Redis does not currently support any kind 
of multi-master replication, so that will not work. Everything should work as 
long as you only have one master.

Perhaps the documentation could be improved regarding this. Not sure.

Hi redis,
Thanks for your response. yes, Each server is a slave of the other, at the
same time, Each server is a master of the other. the scenario I mentioned is
that the two servers is as the role of master and slave of each other. I
hope they can support that when I write data into any server, the data can
be sychronized to other servers. Because as far the redis only support when
I write data or publish data in master server, the data can be sychronized
or received in other slave server which mornitor the subscription operation.

so , I hope in the future the redis can support the below features,
1) multi-master configruation and  replication in same application.
2) when I write and publish data into the slave server, the data can be
sychronized to any server.

thanks to let me know the result about the sepcial scenario  just I
mentioned, so I only modify the architecture of project in order to meet the
feature of redis.

Best Regests,
weiming

No problem. It's always nice when people show an interest in Redis! 
Multi-master replication could perhaps be an interesting feature to have at 
some point... There seem to be others interested in that too.

Hey, we plan to go for cluster to start, that also allows for high availability 
(but at least three nodes are needed). If this solution will not be good enough 
for standard HA setups we'll look at multi-master.

Cheers!

To respond back to weiming: if you have two Redis instances that are slaving 
against each other, I'm surprised you can run any commands against them at all. 
To me, it would seem like you would get a command loop, where a command to 
instance A would sync to B, then back to A again.

Without doing anything else, you should watch how quickly the 'commands 
processed' output from INFO increments with your current configuration.
