Abstract

A method, a system, and a computer program product for analysis of query filtering mechanisms for table fragments. A query plan for execution of a query is generated. The query requires access to at least one table stored in a database system. The query includes one or more filter predicates. The table is partitioned into a plurality of fragments. A determination whether a fragment in the table is compressed and whether the fragment is associated with an index is made. A filter predicate is selected for processing the fragment. For the selected filter predicate, a filter evaluation of the selected filter predicate for the fragment is determined. The filter evaluation of the selected predicate is executed for the fragment.
