public interface SqlOperatorConversion

  • Method Details

    • calciteOperator

      org.apache.calcite.sql.SqlOperator calciteOperator()
      Returns the SQL operator corresponding to this function. Should be a singleton.
      Returns:
      operator

    • toDruidExpression

      @Nullable DruidExpression toDruidExpression(PlannerContext plannerContext, RowSignature rowSignature, org.apache.calcite.rex.RexNode rexNode)
      Translate a Calcite RexNode to a Druid expression.
      Parameters:
      plannerContext - SQL planner context
      rowSignature - signature of the rows to be extracted from
      rexNode - expression meant to be applied on top of the rows
      Returns:
      Druid expression, or null if translation is not possible
      See Also:

    • toDruidExpressionWithPostAggOperands

      @Nullable default DruidExpression toDruidExpressionWithPostAggOperands(PlannerContext plannerContext, RowSignature rowSignature, org.apache.calcite.rex.RexNode rexNode, PostAggregatorVisitor postAggregatorVisitor)
      Translate a Calcite RexNode to a Druid expression, with the possibility of having postagg operands.
      Parameters:
      plannerContext - SQL planner context
      rowSignature - signature of the rows to be extracted from
      rexNode - expression meant to be applied on top of the rows
      postAggregatorVisitor - visitor that manages postagg names and tracks postaggs that were created as by the translation
      Returns:
      Druid expression, or null if translation is not possible
      See Also:

    • toDruidFilter

      @Nullable default DimFilter toDruidFilter(PlannerContext plannerContext, RowSignature rowSignature, @Nullable VirtualColumnRegistry virtualColumnRegistry, org.apache.calcite.rex.RexNode rexNode)
      Returns a Druid filter corresponding to a Calcite RexNode used as a filter condition.
      Parameters:
      plannerContext - SQL planner context
      rowSignature - input row signature
      virtualColumnRegistry - re-usable virtual column references
      rexNode - filter expression rex node
      Returns:
      filter, or null if the call cannot be translated to a filter

    • toPostAggregator

      @Nullable default PostAggregator toPostAggregator(PlannerContext plannerContext, RowSignature querySignature, org.apache.calcite.rex.RexNode rexNode, PostAggregatorVisitor postAggregatorVisitor)
      Returns a Druid PostAggregator corresponding to a Calcite RexNode used to transform a row after aggregation has occurred.
      Parameters:
      plannerContext - SQL planner context
      querySignature - signature of the rows to be extracted from
      rexNode - expression meant to be applied on top of the rows
      postAggregatorVisitor - visitor that manages postagg names and tracks postaggs that were created by the translation
      Returns:
      filter, or null if the call cannot be translated
