Expand description

Table join operations.

Implementations§

Source§

impl TableJoin

Source

pub fn hash_join( left: &InMemoryTable, right: &InMemoryTable, left_key: &str, right_key: &str, join_type: JoinType, ) -> Result<InMemoryTable>

Hash join two tables on the given key columns.

Source

pub fn merge_join( left: &InMemoryTable, right: &InMemoryTable, left_key: &str, right_key: &str, ) -> Result<InMemoryTable>

Merge join two pre-sorted tables on the given key columns. Both tables must already be sorted ascending by their key columns.
