Do you know {{org.codehaus.mojo:native-maven-plugin}}? It allows JNI
compilation on almost all platforms directly from Maven and does not interfere
with SWIG - have used it on OSX, Linux, Win and Solaris.

> Serializing Row cache alternative (Fully off heap)

> Currently SerializingCache is partially off heap, keys are still stored in
> JVM heap as BB,
> * There is a higher GC costs for a reasonably big cache.
> * Some users have used the row cache efficiently in production for better
> results, but this requires careful tunning.
> * Overhead in Memory for the cache entries are relatively high.
> So the proposal for this ticket is to move the LRU cache logic completely off
> heap and use JNI to interact with cache. We might want to ensure that the new
> implementation match the existing API's (ICache), and the implementation
> needs to have safe memory access, low overhead in memory and less memcpy's
> (As much as possible).
> We might also want to make this cache configurable.
