Version 3.2.1 of LMAX Disruptor now ready for download on Maven Central, complete with build and IDE updates.

Version 3.2.1 of  concurrency framework LMAX
 Disruptor, designed for high-performance and low-latency
transaction processing, has just gone live. Project Developer
Michael Barker announced that the latest release is now available
for download on Maven Central via a Google Group
mail
.

Besides build and IDE updates, Disruptor has undergone
a rewrite of  performance tests to run without JUnit and
separate Queues into their own tests. Additionally, there are new
performance tests for immutable message example and new performance
tests for off-heap example.

This highly scalable system offers incredibly low
latency, and is completely written in Java. It’s
developed by the crew at the London MTF (Multilateral Trading
Facility) LMAX trading platform.

The software has been making ‘disruptions’ in the
Javasphere since its launch. It garnered the team behind it a
Duke’s
Choice Award
in 2011, bringing the niche technology to the
attention of a far wider audience than originally intended, and
attracting a good deal more Java devs to the LMAX fold.

At the heart of its framework is a ring buffer data
structure. Behind this is a ring buffer, which is tailored for
high-performance use in the trading area. You can find out more
about the Disruptor, which is offered under Apache 2.0 license, on
its project
page
.

to the framework and the ring buffer, check out this talk:
“Understanding the Disruptor – A Beginner’s Guide to Hardcore
Concurrency”. which was filmed at JAX London 2011.
