David Reiss commented on THRIFT-719:
------------------------------------
This is how the C++ TNonblockingServer works.
> Update Nonblocking and HsHa server to avoid an extra buffer copy
> ----------------------------------------------------------------
>
> Key: THRIFT-719
> URL: https://issues.apache.org/jira/browse/THRIFT-719
> Project: Thrift
> Issue Type: Improvement
> Affects Versions: 0.3
> Reporter: Bryan Duxbury
> Assignee: Bryan Duxbury
> Fix For: 0.3
>
>
> Nonblocking and HsHa servers are currently built in such a way that the
> memory buffer transport that actually contains the whole read message will be
> wrapped in a new TFramedTransport, which means the first time that you read
> from this transport, you'll end up copying the whole buffer again.
> I'd like to just use a straight TMemoryInputTransport, and stop offering the
> option of specifying an input transport factory. Doing so is simple, but it
> has one side effect: you wouldn't be able to customize that transport through
> use of a Transport Factory. However, I think that it's just too likely
> someone will screw up either the functionality or the performance of the
> server by doing so.
