Thomas Jungblut commented on HAMA-559:
--------------------------------------
MapOutputBuffer has asynchronous spilling behaviour, we could use that
technique for this.
> Add a caching message queue
> ---------------------------
>
> Key: HAMA-559
> URL: https://issues.apache.org/jira/browse/HAMA-559
> Project: Hama
> Issue Type: New Feature
> Components: bsp core
> Affects Versions: 0.5.0
> Reporter: Thomas Jungblut
> Priority: Minor
>
> 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.
