---------------------------------------

Also it might be worth to be split in different implementations for some of its options.

> Classes of type {code}org.infinispan.commands.read.GetKeyValueCommand{code} have an high cost in terms of memory allocation.
> Would be great if we could reduce the runtime cost: in an app server test of just 25 minutes - which is stressing way more systems than just Infinispan - just the occasional get operations 43GB of memory accumulated over time.
> This is a high cost on the TLABs, skewing various other values, among others making the default GC options unsuitable.
