ryan rawson commented on HBASE-794:
-----------------------------------
we also need to verify exactly how much garbage serialization/deserialization
does. Our initial thought with the KeyValue patches (HBASE-1234) is to use a
raw protocol that is totally custom and wouldnt require copying data over and
over inside the server. My own tests show that GC overhead is a significant
part of HBase, it would be nice to do a data recv() then not copy that and use
KeyValue instead of object conversion. Stack notes that in this profiling, a
substantial amount of CPU time goes into marshall/demarshall code.

> Key: HBASE-794
> URL: https://issues.apache.org/jira/browse/HBASE-794
> Project: Hadoop HBase
> Issue Type: New Feature
> Components: client, ipc, master, regionserver
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Priority: Minor
>
> This issue considers making a language neutral IPC mechanism and wire format
> a first class component of HBase architecture. Clients could talk to the
> master and regionserver using this protocol instead of HRPC at their option.
> Options for language neutral IPC include:
> * Thrift: http://incubator.apache.org/thrift/
> * Protocol buffers: http://code.google.com/p/protobuf/
> * XDR: http://en.wikipedia.org/wiki/External_Data_Representation
