Suraj Menon commented on HAMA-559:
----------------------------------

How about trying out different message queue implementations based on external dependencies
in the contrib area?

> After HAMA-521 is done, we can add a caching queue which just holds the messages in RAM
that fit into the heap space. The rest can be flushed to disk.
> We may call this a HybridQueue or something like that.
> The benefits should be that we don't have to flush to disk so often and get faster. However
we may have more GC so it is always overall faster.
