Retrieving local data
Hi people,
I was needing to retrieve some data in a local machine that was running
cassandra.
I start the Cassandra's daemon with my java process, so now I need to
execute a CQL, but just in data that was storaged in that machine, is it
possible? How?
Thanks

Yes.
You can get the token ranges via astynax and only ask for rows that are within the token ranges.

Ok aaron. But the problem is that I am running Cassandra 1.1.8. I am using
it for the compatibility with Astyanax 1.56. So, it is possible in
Cassandra 1.1.8, too?

Take a look at the token function with the select statement http://www.datastax.com/docs/1.2/cql_cli/cql/SELECT
