Mark filters with "local only" to avoid sending to coordinator

    XMLWordPrintableJSON

Details

    Description

      If a filter is

      a) produced by a broadcast join and
      b) applied by a scan in the same fragment

      there is no need to send it to the coordinator. If the FE can identify these filters, the BE can do short-circuit application and not send it the coordinator.

      This will interact with IMPALA-3024, as it will be important not to reduce the set of filter producers if the filter will only ever be short-circuited.
