Voldemort 0.90 release branch has been cut. Many new features, enhancements and bug fixes have been introduced in this release including, but not limited to:
* Support for topology ("zone") aware routing (see https://github.com/voldemort/voldemort/wiki/Multi-datacenter-capability for more details) * Support for hinted handoff, including as a method for restoring consistency after a partition between different zones without incurring additional latency of cross-zone quorums necessary for read repair * NIO based client with a pipeline based routing layer (PipelineRoutedStore) * Many improvements to the read only storage engine, including support for online rebalancing of read only stores
Documentation describing these features in more detail (on the wiki and the project website/blog) will be coming shortly.
Please feel free to check the new release out and experiment with it. Once the release branch has been deemed stable (i.e., no further check-ins of bug fixes are expected), release notes will be upgraded, builds will be posted on the official downloads page and the release-090 branch will be merged back into the master branch.

I have your patch in a special branch, but as I've mentioned, there's a unit test failure in that branch. Once the test failure is fixed (the test is originally written by Bhupesh), I'll merge that branch into the release branch.

I have noticed other bugs during more rebalancing testing. I'll include unit test and patches to others bugs too. I'll be sending you additional diff's based on https://github.com/afeinberg/voldemort/tree/issue-288 branch

No issue in this, zone-routing is done on the client side. It should also work with server side routing, but we haven't tested that as much.
You will have to upgrade the clients, however, to 0.91 before you enable zone routing. I suggest updating clients first and then servers (for a zero-downtime release).
