Jonathan Ellis commented on CASSANDRA-1908:
-------------------------------------------
The page Hiram linked says "JNA supports a direct mapping method which can
improve performance substantially, approaching that of custom JNI." This is
the approach we are using (Native.register, instead of the slower
Native.loadLibrary).
> Implement the CLibrary using JNI module to avoid the LGPL dependency on JNA

> Key: CASSANDRA-1908
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1908
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Hiram Chirino
> Fix For: 0.7.1
>
> Attachments: cassandra-jni.zip
>
>
> Cassandra can't ship JNA out of the box since it's LGPL licensed, so many of
> the performance optimizing features in the CLibrary class are not available
> in a simple install. It should be trivial to implement a real JNI library
> for the CLibrary class.
