Module physical_planner 

Planner for LogicalPlan to ExecutionPlan

Structs

DefaultPhysicalPlanner

Default single node physical query planner that converts a LogicalPlan to an ExecutionPlan suitable for execution.

ExecutionPlanChild 🔒

InvariantChecker 🔒

Check ExecutionPlan invariants per InvariantLevel.

LogicalNode 🔒

OptimizationInvariantChecker 🔒

Enums

ChildrenContainer 🔒

To avoid needing to pass single child wrapped in a Vec for nodes with only one child.

NodeState 🔒

PlanAsyncExpr 🔒

PlannedExprResult 🔒

Traits

ExtensionPlanner

This trait exposes the ability to plan an ExecutionPlan out of a LogicalPlan.

PhysicalPlanner

Physical query planner that converts a LogicalPlan to an ExecutionPlan suitable for execution.

Functions

create_aggregate_expr_and_maybe_filter

Create an aggregate expression from a logical expression or an alias

create_aggregate_expr_with_name_and_maybe_filter

Create an aggregate expression with a name from a logical expression

create_cube_physical_expr 🔒

Expand and align a CUBE expression. This is a special case of GROUPING SETS (see https://www.postgresql.org/docs/current/queries-table-expressions.html#QUERIES-GROUPING-SETS)

create_rollup_physical_expr 🔒

Expand and align a ROLLUP expression. This is a special case of GROUPING SETS (see https://www.postgresql.org/docs/current/queries-table-expressions.html#QUERIES-GROUPING-SETS)

create_window_expr

Create a window expression from a logical expression or an alias

create_window_expr_with_name

Create a window expression with a name from a logical expression

get_null_physical_expr_pair 🔒

For a given logical expr, get a properly typed NULL ScalarValue physical expression

get_physical_expr_pair 🔒

is_window_frame_bound_valid

Check if window bounds are valid after schema information is available, and window_frame bounds are casted to the corresponding column type. queries like: OVER (ORDER BY a RANGES BETWEEN 3 PRECEDING AND 5 PRECEDING) OVER (ORDER BY a RANGES BETWEEN INTERVAL ‘3 DAY’ PRECEDING AND ‘5 DAY’ PRECEDING) are rejected

merge_grouping_set_physical_expr 🔒

Expand and align a GROUPING SET expression. (see https://www.postgresql.org/docs/current/queries-table-expressions.html#QUERIES-GROUPING-SETS)

qualify_join_schema_sides 🔒

Qualifies the fields in a join schema with “left” and “right” qualifiers without mutating the original schema. This function should only be used when the join inputs have already been requalified earlier in try_new_with_project_input.

tuple_err 🔒
