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

Scanning isn't always 30 rows small - I personally set my scanner caching to 1000 rows. 

I would set my performance targets at 30-50k ops/sec (what I currently get on my systems). Given the other perf graphs, its probably a question of "will any serialization be fast enough". It'd be nice to get a kb/op measure of garbage gen activity.

With the cms with capped parnew as a stock gc setup, we need to keep garbage gen as low as possible.

> 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
