Shai Erera commented on LUCENE-4615:
------------------------------------
Took a look in the code, the allocators are used mostly by FacetArrays, so
perhaps that can be the abstraction level? I.e. we make FacetArrays expose API
similar to acquire/release of int[]/float[]. The default impl would always
allocate new, and discard in release. A ReusingFacetArrays would use the
current allocators logic?
> Remove Int/FloatArrayAllocator from facet module?

> It makes me nervous to have allocation tied to our public APIs ... and the
> ability for Int/FloatArrayAllocator to hold onto N arrays indefinitely makes
> me even more nervous. I think we should just trust java/GC to do their job
> here and free the storage as soon as faceting is done.
