Implement stats annotation rule for the LateralViewJoinOperator

    XMLWordPrintableJSON

Details

    Description

      StatsRulesProcFactory doesn't have any rules to handle a JOIN by LATERAL VIEW.

      This can cause an underestimation in case that UDTF in LATERAL VIEW generates multiple rows.

      HIVE-20262 has already added the rule for UDTF.

      This issue would add the rule for LateralViewJoinOperator.
