ryan rawson commented on HBASE-794:
-----------------------------------

Perhaps you can outline exactly how you can work around lack of NULLs in thrift 
that does _not_ involve exceptions?  I think it should not be required to use 
exceptions during non-exceptional events - many systems have lower performance 
under thrown exceptions, and the code path is complex.

I just wish that compact binary protocols wasn't a late addition.  It doesn't 
give me confidence by the late addition of what should have been there from day 
one.

> 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
