> I have been doing some profiling of the garbage being created. The idea was
> to follow up on HBASE-14490 and experiment with offheap IPC byte buffers and
> byte buffer re-use. However, without changing the IPC byte buffers for now,
> there are a couple of (easy) improvements that I've identified from
> profiling:
> 1. RPCServer.Connection.processRequest() should work with ByteBuffer instead
> of byte[] and not-recreate CodedInputStream a few times.
> 2. RSRpcServices.getRegion() allocates two byte arrays for region, while only
> 1 is needed.
> 3. AnnotationReadingPriorityFunction is very expensive in allocations. Mainly
> it allocates the regionName byte[] to get the table name. We already set the
> priority for most of the operations (multi, get, increment, etc) but we are
> only reading the priority in case of multi. We should use the priority from
> the client side.
> Lets do the simple improvements in this patch, we can get to IPC buffer
> re-use in HBASE-14490.
