If you are just trying to get a sense of the data, you could try adding a limit clause to limit the amount of results and hopefully beat the timeout. However, ALLOW FILTERING really means "ALLOW ME TO DESTROY MY APPLICATION AND CLUSTER." It means the data model does not support the query and will not scale -- in this case, not even on one node. Design a new table to support the query with a proper partition key (and any clustering keys).

Re: [EXTERNAL] Re: Caused by: com.datastax.driver.core.exceptions.ReadTimeoutException:
As already mentioned in this thread, ALLOW FILTERING should be avoided in any scenario. It seems to work in test scenarios, but as soon as the data increases to certain size(a few MBs), it starts failing miserably and fails almost always.

Re: [EXTERNAL] Re: Caused by: com.datastax.driver.core.exceptions.ReadTimeoutException:
Thank you gentlemen for all your responses. Reading through them I was able to resolve the issue by doing the following, a. Creating an index on one of the query fieldsb. Setting page size to 200 Now the query runs instantaneously.
