I see. The reason I looked at that package was, I need to use the batch feature, and I could not make it work using thrift with the CF having composite key. It worked fine with the simple key, but not composite, I was getting an error while trying to do the update. Sylvain suggested (in reply to my other posting) that I use cql3 batch statement, but I am not sure how to do it efficiently from Java. Can batch statement be prepared? Is it OK to put 10000 of update statements in one batch, with 50000 question marks in it? The set that many variables? Maybe I can try small example first, just to see if it works at all.

Having problem connecting to the server using ClientState. I was not sure what to put in the credentials map (I did not set any users/passwords on my server), so I tried setting empty strings for “username” and “password”, setting them to bogus values, passing null to the login method – there was no difference. It does not complain at the login(), but then it complains about setKeyspace(<my keyspace>), saying that the specified keyspace does not exist (it obviously does exist). The configuration was loaded from cassandra.yaml used by the server. I did not have any problem like this when I used org.apache.cassandra.thrift.Cassandra.Client . What am I doing wrong? I think that package just contains server classes. Everything you need should be in org.apache.cassandra.thrift. To use cql3 I just use the client methods 'execute_cql_query', 'prepare_cql_query' and 'execute_prepared_cql_query', after setting cql version to '3.0.0'. -- Derek Williams ________________________________ This email, along with any attachments, is confidential and may be legally privileged or otherwise protected from disclosure.
