Hello, While digging more for this I've found these : http://svn.apache.org/viewvc/thrift/lib/c_glib/test/ Which shows how to create the TSocket and TTransport structures, very similar to the way it's done in C++. Now I'm stuck on how to create the actual connection to the Cassandra server. It should be a function generated by the Cassandra thrift interface, but I can't seem to find the proper one. Any help would be very much appreciated. Regards, Vlad Mina Naguib<mina.nag...@bloomdigital.com> wrote:Hi Vlad I'm the author of libcassie. For what it's worth, it's in production where I work, consuming a heavily-used cassandra 0.7.9 cluster. We do have plans to upgrade the cluster to 1.x, to benefit from all the improvements, CQL, etc... but that includes revising all our clients (across several programming languages). So, it's definitely on my todo list to address our C clients by either upgrading libcassie, or possibly completely rewriting it. Currently it's a wrapper around the C++ parent project libcassandra. I haven't been fond of having that many layered abstractions, and the thrift Glib2 interface has definitely piqued my interest, so I'm leaning towards a complete rewrite. While we're at it, it would also be nice to have features like asynchronous modes for popular event loops, connection pooling, etc. Unfortunately, I have no milestones set for any of this, nor the time (currently) to experiment and proof-of-concept it. I'd be curious to hear from other C hackers whether they've experimented with the thrift Glib2 interface and gotten a "hello world" to work against cassandra 1.x. Perhaps there's room for some code sharing/collaboration on a new library to supersede the existing libcassie+libcassandra.

The idea is to not play around with including C++ code in a C app, if there's an alternative ( the thrift g_libc ). Unfortunately, since thrift does not generate a skeleton for the glibc code, I don't know how to find out what the API functions are called, and guessing them is not going that good :) I'll wait a little longer& see if anybody can help with the C thrift, or at least tell me it's not working. :) Regards, Vlad Eric Tamme<eta...@gmail.com> wrote:On 12/14/2011 04:18 PM, Vlad Paiu wrote:Hi, Just tried libcassie and seems it's not compatible with latest cassandra, as even simple inserts and fetches fail with InvalidRequestException... So can anybody please provide a very simple example in C for connecting& fetching columns with thrift ?

We use the thrift generated c++ bindings and extern stuff to c. I spoke to bogdan about this a while ago, and gave him the github link, but here it is for your reference https://github.com/junction/db_jnctn_usrloc Hopefully that helps. I idle in #opensips too, just ask about cassandra in there and I'll probably see it. - Eric Tamme
