Struct PhysicalPlan 

pub struct PhysicalPlan { /* private fields */ }

Krishiv physical plan wrapper.

Implementations

impl PhysicalPlan

pub fn new(name: impl Into<String>, kind: ExecutionKind) -> Self

Create an empty physical plan.

pub fn coalesced_partition_count(&self) -> Option<usize>

Return the post-AQE coalesced partition count, if set by CoalesceRule.

pub fn with_coalesced_partition_count(self, count: usize) -> Self

Set the coalesced partition count (called by CoalesceRule::apply).

pub fn add_node(&mut self, node: PlanNode)

Add a node to the plan.

pub fn with_node(self, node: PlanNode) -> Self

Add a node and return the updated plan.

pub fn name(&self) -> &str

Plan name.

pub fn kind(&self) -> ExecutionKind

Plan execution kind.

pub fn nodes(&self) -> &[PlanNode]

Plan nodes (read-only access).

pub fn nodes_mut(&mut self) -> &mut [PlanNode]

Plan nodes (mutable access).

Used by AQE rules such as AutoPartitionRule to adjust partition counts on Exchange nodes without rebuilding the entire plan graph.

pub fn shuffle_partitions(&self) -> Option<u32>

Return the shuffle partition override, if set.

pub fn with_shuffle_partitions(self, n: Option<u32>) -> Self

Set the shuffle partition override for this plan.

pub fn validate(&self) -> Result<(), PlanError>

Validate node identifiers, input references, and graph acyclicity.

pub fn describe(&self) -> String

Compact textual description for early EXPLAIN output.
