Class Summary
Class	Description
Aggregate	Relational operator that eliminates duplicates and computes totals.
Aggregate.AggCallBinding	Implementation of the `SqlOperatorBinding` interface for an `aggregate call` applied to a set of operands in the context of a `LogicalAggregate`.
AggregateCall	Call to an aggregate function within an `Aggregate`.
Calc	`Calc` is an abstract base class for implementations of `LogicalCalc`.
Collect	A relational expression that collapses multiple rows into one.
Correlate	A relational operator that performs nested-loop joins.
CorrelationId	Describes the necessary parameters for an implementation in order to identify and set dynamic variables.
EquiJoin	Deprecated This class is no longer needed; if you are writing a sub-class of Join that only accepts equi conditions, it is sufficient that it extends `Join`.
Exchange	Relational expression that imposes a particular distribution on its input without otherwise changing its content.
Filter	Relational expression that iterates over its input and returns elements for which `condition` evaluates to `true`.
Intersect	Relational expression that returns the intersection of the rows of its inputs.
Join	Relational expression that combines two relational expressions according to some condition.
JoinInfo	An analyzed join condition.
Match	Relational expression that represent a MATCH_RECOGNIZE node.
Match.RexMRAggCall	Aggregate calls in match recognize.
Minus	Relational expression that returns the rows of its first input minus any matching rows from its other inputs.
Project	Relational expression that computes a set of 'select expressions' from its input relational expression.
Project.Flags	Deprecated
RelFactories	Contains factory interface and default implementation for creating various rel nodes.
RelFactories.SnapshotFactoryImpl	Implementation of `RelFactories.SnapshotFactory` that returns a vanilla `LogicalSnapshot`.
RelFactories.Struct	Immutable record that contains an instance of each factory.
RepeatUnion	Relational expression that computes a repeat union (recursive union in SQL terminology).
Sample	Relational expression that returns a sample of the rows from its input.
SetOp	`SetOp` is an abstract base for relational set operators such as UNION, MINUS (aka EXCEPT), and INTERSECT.
Snapshot	Relational expression that returns the contents of a relation expression as it was at a given time in the past.
Sort	Relational expression that imposes a particular sort order on its input without otherwise changing its content.
SortExchange	Relational expression that performs `Exchange` and `Sort` simultaneously.
Spool	Relational expression that iterates over its input and, in addition to returning its results, will forward them into other consumers.
TableFunctionScan	Relational expression that calls a table-valued function.
TableModify	Relational expression that modifies a table.
TableScan	Relational operator that returns the contents of a table.
TableSpool	Spool that writes into a table.
Uncollect	Relational expression that unnests its input's columns into a relation.
Union	Relational expression that returns the union of the rows of its inputs, optionally eliminating duplicates.
Values	Relational expression whose value is a sequence of zero or more literal row values.
Window	A relational expression representing a set of window aggregates.
Window.Group	Group of windowed aggregate calls that have the same window specification.
Window.RexWinAggCall	A call to a windowed aggregate function.

Enum Summary
Enum	Description
Aggregate.Group	Describes the kind of roll-up.
JoinRelType	Enumeration of join types.
Spool.Type	Enumeration representing spool read / write type.
TableModify.Operation	Enumeration of supported modification operations.
