Jason Rutherglen commented on HBASE-4018:
-----------------------------------------
I understand the problem you're trying to solve here a little better, eg, the
block cache and the GC. Perhaps JNA [1] can also be used for this use case, eg
[2] enables direct creation and destruction of an array (unlike direct byte
buffers which doesn't enable 'direct' destruction).

> Currently, block caches are limited by heap size, which is limited by garbage
> collection times in Java.
> We can get around this by using memcached w/JNI as a secondary block cache.
> This should be faster than the linux file system's caching, and allow us to
> very quickly gain access to a high quality slab allocated cache.
