Re: Reading old data problem
Ok guys let me try to ask it in a different way: Will repair totally ensure a data synchronism among nodes? Extra question: Once I write at CL=All, will C* ensure that I can read from ANY node without an inconsistency? The reverse state, writing at CL=One but reading at CL=All will also ensure that?

What I'm missing? Thanks in advance!

If there are no writes happening on the cluster then yes. Otherwise, the answer is it depends since all the normal things that lead to inconsistencies can still happen. Extra question: Once I write at CL=All, will C* ensure that I can read from ANY node without an inconsistency? The reverse state, writing at CL=One but reading at CL=All will also ensure that? You can get consistent behavior if CL.read + CL.write RF. So since you have just 2 nodes and RF=2, you'd need to have at least CL.read=2 and CL.write=1 or CL.read=1 and CL.write=2. -Bryan On Wed, Feb 27, 2013 at 11:24 PM, Víctor Hugo Oliveira Molinar vhmoli...@gmail.com wrote: Hello, I need some help to manage my live cluster!
