Class Summary

Class	Description
CalcPythonCorrelateTransposeRule	Rule will transpose the conditions after the Python correlate node if the join type is inner join.
FlinkAggregateExpandDistinctAggregatesRule	Planner rule that expands distinct aggregates (such as COUNT(DISTINCT x)) from a Aggregate.
FlinkAggregateJoinTransposeRule	Planner rule that pushes an Aggregate past a Join.
FlinkAggregateRemoveRule	Planner rule that removes a Aggregate if its aggregate functions are SUM, MIN, MAX, AUXILIARY_GROUP with no filterArgs, and the underlying relational expression is already distinct.
FlinkJoinPushExpressionsRule	Planner rule that pushes down expressions in "equal" join condition.
FlinkLogicalCalcRemoveRule	Rule to remove trivial FlinkLogicalCalc.
FlinkProjectJoinTransposeRule	Planner rule that pushes a Project past a Join by splitting the projection into a projection on top of each child of the join.
FlinkSemiAntiJoinFilterTransposeRule	Planner rule that pushes semi-join down in a tree past a Filter.
FlinkSemiAntiJoinJoinTransposeRule	Planner rule that pushes a org.apache.calcite.rel.core.SemiJoin down in a tree past a Join in order to trigger other rules that will convert SemiJoins.
FlinkSemiAntiJoinProjectTransposeRule	Planner rule that pushes a org.apache.calcite.rel.core.SemiJoin down in a tree past a Project.
JoinTableFunctionScanToCorrelateRule	Rule that rewrites Join on TableFunctionScan to Correlate.
ProjectSnapshotTransposeRule	Transpose LogicalProject past into LogicalSnapshot.
ProjectWatermarkAssignerTransposeRule	Transpose between the LogicalWatermarkAssigner and LogicalProject.
ProjectWindowTableFunctionTransposeRule	Planner rule that pushes a LogicalProject into a LogicalTableFunctionScan which contains a Window table function call by splitting the projection into a projection on top of child of the TableFunctionScan.
PushFilterInCalcIntoTableSourceScanRule	Pushes a filter condition from the FlinkLogicalCalc and into a FlinkLogicalTableSourceScan.
PushFilterIntoSourceScanRuleBase	Base class for rules that push down filters into table scan.
PushFilterIntoTableSourceScanRule	Planner rule that tries to push a filter into a LogicalTableScan, which table is a TableSourceTable.
PushLimitIntoTableSourceScanRule	Planner rule that tries to push limit into a FlinkLogicalTableSourceScan, which table is a TableSourceTable.
PushPartitionIntoTableSourceScanRule	Planner rule that tries to push partition evaluated by filter condition into a LogicalTableScan.
PushProjectIntoTableSourceScanRule	Pushes a LogicalProject into a LogicalTableScan.
PushWatermarkIntoTableSourceScanAcrossCalcRule	Rule to push the FlinkLogicalWatermarkAssigner across the FlinkLogicalCalc to the FlinkLogicalTableSourceScan.
PushWatermarkIntoTableSourceScanRule	Rule to push the FlinkLogicalWatermarkAssigner into the FlinkLogicalTableSourceScan.
PushWatermarkIntoTableSourceScanRuleBase	Base rule for interface SupportsWatermarkPushDown and SupportsSourceWatermark.
PythonCorrelateSplitRule	Rule will split the Python FlinkLogicalTableFunctionScan with Java calls or the Java FlinkLogicalTableFunctionScan with Python calls into a FlinkLogicalCalc which will be the left input of the new FlinkLogicalCorrelate and a new FlinkLogicalTableFunctionScan.
PythonMapMergeRule	Rule will merge Python FlinkLogicalCalc used in Map operation, Flatten FlinkLogicalCalc and Python FlinkLogicalCalc used in Map operation together.
PythonMapRenameRule	Rule which renames the field names of the Flatten FlinkLogicalCalc which is right after a FlinkLogicalCalc representing a Python Map operation to the output names of the map function.
RedundantRankNumberColumnRemoveRule	Planner rule that removes the output column of rank number iff the rank number column is not used by successor calc.
RemoveUnreachableCoalesceArgumentsRule	Removes unreachable BuiltInFunctionDefinitions.COALESCE arguments.
SubQueryDecorrelator	SubQueryDecorrelator finds all correlated expressions in a SubQuery, and gets an equivalent non-correlated relational expression tree and correlation conditions.
SubQueryDecorrelator.Result	Result describing the relational expression after decorrelation and where to find the equivalent non-correlated expressions and correlated conditions.
SubQueryDecorrelator.SubQueryRelDecorrelator	Pull out all correlation conditions from a given subquery to top level, and rebuild the subquery rel tree without correlation conditions.
WrapJsonAggFunctionArgumentsRule	Transforms JSON aggregation functions by wrapping operands into BuiltInFunctionDefinitions.JSON_STRING.
