Eric Evans commented on CASSANDRA-1908:
---------------------------------------
bq. The JNA solution has all the same architecture dependent code for N
platform problems, what's worse is that it's using a FFI and your hoping that
everything maps out right.
Sure, but someone else is doing that work for us. And as Jonathan mentioned,
JNA is package for all architectures on the most common platforms.
bq. Additionally, because of the FFI, the JNI interface is going to be orders
of magnitude more efficent. See: https://jna.dev.java.net/#performance
Performance is always a good argument to make. Do you have before/after
numbers to show that it will make a substantial difference for us?

> 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.
