Subject [jira] [Commented] (HBASE-1015) pure C and C++ client libraries
Date Thu, 17 Jan 2013 18:10:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556423#comment-13556423
] 

Nick Dimiduk commented on HBASE-1015:
-------------------------------------

bq. The scope of building a C client is not just the transport, it's also duplicating or replacing
all of the functionality of the fat Java client.

Agreed; I mean the construction of a fully-featured client implementation available via C,
not just transport. I've been out of C/C++ for a number of years, I'm entirely ignorant on
C++11 so I cannot comment on implementation details. I do know that it's fairly common-place
to wrap a C++ library with C bindings, so that decision can be left up to the implementor.

> If via HBASE-794 first class support for talking via Thrift directly to HMaster and HRS
is available, then pure C and C++ client libraries are possible. 
> The C client library would wrap a Thrift core. 
> The C++ client library can provide a class hierarchy quite close to o.a.h.h.client and,
ideally, identical semantics. It  should be just a wrapper around the C API, for economy.
> Internally to my employer there is a lot of resistance to HBase because many dev teams
have a strong C/C++ bias. The real issue however is really client side integration, not a
fundamental objection. (What runs server side and how it is managed is a secondary consideration.)
