After figuring out how to use the ">" operator on an secondary index I noticed that in a column family of about 5.5 million datasets I get a rpc_timeout when trying to read data from this table. In the concrete situation I want to request data younger than January 1 2013. The number of rows that should be affected are about 1 million. When doing the request I get a timeout error:
cqlsh:demodb> select * from ola where date > '2013-01-01' and hour = 0 limit 10 allow filtering; Request did not complete within rpc_timeout. Actually I find this very confusing since I would except an exceptional performance gain in comparison to a similar sql query. Therefore, I think the query I'm performing is not appropriate for cassandra, although I would do a query like that in this manner on a sql database. So my question now is: How should I perfrom this query on cassandra?
