Struct HashJoinExecNode 

pub struct HashJoinExecNode {
    pub left: Option<Box<PhysicalPlanNode>>,
    pub right: Option<Box<PhysicalPlanNode>>,
    pub on: Vec<JoinOn>,
    pub join_type: i32,
    pub partition_mode: i32,
    pub null_equality: i32,
    pub filter: Option<JoinFilter>,

Fields

left: Option<Box<PhysicalPlanNode>>

right: Option<Box<PhysicalPlanNode>>

on: Vec<JoinOn>

join_type: i32

partition_mode: i32

null_equality: i32

filter: Option<JoinFilter>

projection: Vec<u32>

null_aware: bool

dynamic_filter: Option<PhysicalExprNode>

Optional dynamic filter expression for pushing down to the probe side.

fetch: Option<u64>

Optional row limit pushed into the join by the limit_pushdown rule.

This is presence-tracked (optional) on purpose: messages produced by versions predating this field carry no fetch at all, and a plain proto3 scalar would decode that absence as 0, i.e. “fetch 0 rows”, silently turning old plans into empty results. With optional, absent decodes to None, which is the correct reading of an older message.

Implementations

impl HashJoinExecNode

Returns the enum value of partition_mode, or the default if the field is set to an invalid enum value.

pub fn set_partition_mode(&mut self, value: PartitionMode)

Sets partition_mode to the provided enum value.

pub fn null_equality(&self) -> NullEquality

Returns the enum value of null_equality, or the default if the field is set to an invalid enum value.

pub fn set_null_equality(&mut self, value: NullEquality)

Sets null_equality to the provided enum value.

pub fn fetch(&self) -> u64

Returns the value of fetch, or the default value if fetch is unset.
