Enum PartitionMode 

pub enum PartitionMode {
    Partitioned,
    CollectLeft,
    Auto,
}

Hash join Partitioning mode

Variants

Partitioned

Left/right children are partitioned using the left and right keys

CollectLeft

Left side will collected into one partition

Auto

DataFusion optimizer decides which PartitionMode mode(Partitioned/CollectLeft) is optimal based on statistics. It will also consider swapping the left and right inputs for the Join

Trait Implementations

impl Clone for PartitionMode

fn clone(&self) -> PartitionMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PartitionMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PartitionMode

fn eq(&self, other: &PartitionMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
