ZooKeeper is a high-performance coordination service for distributed applications. It exposes common services - such as naming, configuration management, synchronization, and group services - in a simple interface so you don't have to write them from scratch. You can use it off-the-shelf to implement consensus, group management, leader election, and presence protocols. And you can build on it for your own, specific needs.
Key features of the 3.2.0 release: * client side bindings for; Perl, Python, & REST * flexible quorum support * re-usable recipe code libraries * chroot support in connect string * many fixes, improvements, improved documentation, etc...A number of optimizations have gone into this release and our benchmarks show that read/write performance of version 3.2.0 is approximately twice that of the previous 3.1.0 version!
