Enhanced FILTER optimizer

    XMLWordPrintable

    Details

      Description

      It would be nice to have more sophisticated optimization strategies for FILTER expressions. This optimizer may apply strategies such as


      - the elimination of duplicate filter expressions,
      - decomposition of complex conjunctive filter expressions (to make the components pushable independently),
      - reordering of filters (where it makes sense)
      - etc.

      The optimizer should run before running the ASTAttachJoinFilterRewriter, and improve the outcome of the latter.
