Great. Thanks Billie. I'll have to dig into our algorithms a bit more to determine if a pure Java implementation can compete with a JNI + C++ implementation. Generally I think Java keeps up, but we may be doing some heavy math that is just plain faster in C++.

In my case we have some C++ code that we'd like to leverage for a FilteringIterator, but we'd prefer not to port it over to Java, and we'd like to avoid JNI if we can. No, there isn't an easy way to do that. It would be possible to use Hadoop pipes with Accumulo by manually deserializing Keys, but that wouldn't help for an Iterator. If you go the JNI route, taking a look at the native map code might be helpful. Billie Thanks, Tejay
