Erik, is that a patch to Thrift? Or just a configuration?
Thanks,

Hello,
I run some tests with C# and Hbase using Thrift. By default
reads/writes were slow (~10/s). After modifying
Thrift.Transport.TSocket class to use BufferedStream, speed increased
a lot (more than 1000 per second). Maybe that helps.
Thanks,
Erik

As Jonathan Gray said, it is not on our roadmap currently, so
we have not looked at ways to do it. However, JCC is Apache
2.0 license so it is a possible approach.

I stumbled on JCC, the Java->C++ (and Python) bridge that the PyLucene
folk are using: http://svn.osafoundation.org/pylucene/trunk/jcc/jcc/README
Any thoughts on perhaps using that for the Hadoop family of projects?

What have others seen with thrift?
There are talks of a new client-side API. To my knowledge no one is
working
on this, so it is not currently scheduled for any upcoming release.
There
are a number of people who would be interested in it, so please continue
discussion on the issue if you have an interest in it.
Here is the open issue regarding this (Pure C/C++ client libraries):

Subject: Thrift API vs Java API
Hi.Currently i'm trying to communicate with Hbase from .NET environment
and
the only option that i have is Thrift.
I did small comparison (execution time) between Java and Thrift (adding
1000
rows with 1k data) and Java is 3.4 ms (average) vs. Thrift that is 44
ms
average.
It seems that Thrift option is not usable from performance aspect.
Now he question : some one tried to implement Hbase client side in C++
/
.NET ? Is it feasible ?
Best Regards.
