HyperDex 1.4 Release Announcement

[Robert Escriva]

We are proud to announce HyperDex 1.4, the next generation NoSQL data
store that provides ACID transactions, schema-less documents,
fault-tolerance, and high-performance. Some key features of HyperDex
are:

- High Performance: HyperDex is fast. It outperforms MongoDB and
Cassandra on industry-standard benchmarks by a factor of 2X or more.

- Advanced Functionality: With the Warp add-on, HyperDex offers
multi-key transactions that span multiple objects with ACID
guarantees.

- Strong Consistency: HyperDex ensures that every GET returns the
result of the latest PUT.

- Fault Tolerance: HyperDex automatically replicates data to tolerate a
configurable number of failures.

- Scalable: HyperDex automatically redistributes data to make use of
new resources as you add more nodes to your cluster.

This release brings the following changes and improvements:

- Improved Performance: Concurrency improvements in HyperLevelDB
provide higher throughput to concurrent applications.

- Improved Performance: A new on-disk format and improved replication
protocol offer higher performance to all applications

- Improved Fault Tolerance: The fault tolerance code has been
refactored to reduce time to recovery, especially under massive
correlated failures.

- Improved Go Bindings: The Go bindings are up-to-date with other
languages.

- New utility: It is now possible to rename spaces with the "hyperdex
mv-space" command.

HyperDex runs on 64-bit Linux (Ubuntu, Debian, Fedora, Centos) and OS X.
Binary packages for Debian 7, Ubuntu 12.04,14.04, Fedora 19-20, and
CentOS 6 are available [1], as well as source tarballs for other Linux
platforms.

This release provides bindings for C, C++, Python, Node.js, Java, Ruby,
and Go.

An evaluation version of Warp, and Warp bindings for Python, Java, and
Ruby are available in the HyperDex repository. Install the
"hyperdex-warp" package in your package manager to switch from HyperDex
to Warp and test out the evaluation version.

Happy Hacking,
The HyperDex Team
