Module plan 

Logical plan types

Structs

Aggregate

Aggregates its input based on a set of grouping and aggregate expressions (e.g. SUM).

Analyze

Runs the actual plan, and then prints the physical plan with with execution metrics.

ColumnUnnestList

Represent the unnesting operation on a list column, such as the recursion depth and the output column name after unnesting

DescribeTable

Describe the schema of table

DistinctOn

Removes duplicate rows from the input

EmptyRelation

Relationship produces 0 or 1 placeholder rows with specified output schema In most cases the output schema for EmptyRelation would be empty, however, it can be non-empty typically for optimizer rules

Explain

Produces a relation with string representations of various parts of the plan

ExplainOption

Options for EXPLAIN

Extension

Extension operator defined outside of DataFusion

Filter

Filters rows from its input that do not match an expression (essentially a WHERE clause with a predicate expression).

Join

Join two logical plans on one or more join columns

Limit

Produces the first n tuples from its input and discards the rest.

Projection

Evaluates an arbitrary list of expressions (essentially a SELECT with an expression list) on its input.

RecursiveQuery

A variadic query operation, Recursive CTE.

Repartition

Sort

Sorts its input according to a list of sort expressions.

StringifiedPlan

Represents some sort of execution plan, in String form

Subquery

Subquery

SubqueryAlias

Aliased subquery

TableScan

Produces rows from a table provider by reference or from the context

Union

Union multiple inputs

Unnest

Unnest a column that contains a nested list type. See UnnestOptions for more details.

Values

Values expression. See Postgres VALUES documentation for more details.

Window

Window its input based on a set of window spec and window function (e.g. SUM or RANK)

Enums

Distinct

Removes duplicate rows from the input

FetchType

Different types of fetch expression in Limit plan.

JoinConstraint

Join constraint

JoinType

Join type

LogicalPlan

A LogicalPlan is a node in a tree of relational operators (such as Projection or Filter).

Partitioning

Logical partitioning schemes supported by LogicalPlan::Repartition

PlanType

Represents which type of plan, when storing multiple for use in EXPLAIN plans

SkipType

Different types of skip expression in Limit plan.

Traits

ToStringifiedPlan

Trait for something that can be formatted as a stringified plan

Functions

calc_func_dependencies_for_aggregate 🔒

Calculates functional dependencies for aggregate expressions.

calc_func_dependencies_for_project 🔒

This function projects functional dependencies of the input plan according to projection expressions exprs.

contains_grouping_set 🔒

Checks whether any expression in group_expr contains Expr::GroupingSet.

get_unnested_columns 🔒

get_unnested_list_datatype_recursive 🔒

projection_schema

Computes the schema of the result produced by applying a projection to the input logical plan.
