Abstract
A method and system for parallel query processing is provided. The method includes estimating a number of sub-queries that may be formed corresponding to an input query. The method further includes fragmenting the input query into a plurality of sub queries by adding one or more filter predicates to the input query without altering the semantics of the input query. Further, processing of the sub queries is scheduled. Thereafter, one or more query execution plans are generated and processed. Following the processing of the query execution plans, the results of the processed sub queries are collated, aggregated and presented in a required format.
