Add RuntimeFilters for min/max at KuduScanNode

    XMLWordPrintableJSON

Details

    Description

      Kudu scans will benefit significantly from runtime filters. For now, we could generate min/max values instead of bloom filters to push to the KuduScanNode and, with support from the Kudu client (KUDU-1683), we could push them to Kudu during execution. At some point, it would be nice to push bloom filters to Kudu (IMPALA-3741), but that will require more work and should be a potential follow-up task to this.
