Abstract
Described herein is a computer implemented method. The method comprises generating a subscription identifier based on an original SQL query and determining if a set of first stage query results is associated with the subscription identifier in a cache. If so, the method further comprises generating a second stage SQL query based on a second subset of the plurality of clauses and the set of first stage query results, causing execution of the second stage SQL query to obtain a set of second stage query results from a database, and returning the set of second stage query results.
