Subject [ANNOUNCE] Apache DirectMemory 0.2
Date Tue, 17 Sep 2013 04:58:58 GMT

The Apache DirectMemory Team would like to announce the 0.2 release.

Apache DirectMemory is a multi layered cache implementation featuring
off-heap memory management to enable efficient handling of a large
number of java objects without affecting jvm garbage collection

It's a technology preview release. So some APIs can be change in the future.

We hope you enjoy using Apache DirectMemory! If you have any
