How to increase timeout for queries in Hector?

Question

Im using HFactory.createRangeSlicesQuery and set rows count to 1 million (with setRowCount() method), but get a TimedOutException().

Is there a way to set the timeout from client?

I have tried various setters in CassandraHostConfigurator but it didnt help.

Answer 1

You should increase the rpc_timeout setting in cassandra.yaml meaning you config the setting server-side per each node. Checkout this thread for some more details.

Answer 2

Instead of increasing the timeout, you should page through your data in smaller batches.

CQL clients like the native Java driver do this automatically: http://www.datastax.com/dev/blog/cql-in-cassandra-2-0
