Abstract
A method, in a continuous computation system, for processing a set of registered queries over a cluster of servers includes creating an execution plan for processing a set of queries over a cluster of servers, where the continuous computation system creates the execution plan by analyzing the semantics and requirements of the queries to determine how to distribute processing across the cluster. Analysis of a query can include determining whether input messages for the query can be processed independent of each other, whether input messages for the query can be partitioned into groups that can be processed independent of each other, whether the query includes an aggregator function, and whether the query includes a subquery.
