Fields

join_type: i32

left_key: Vec<i32>

right_key: Vec<i32>

left_table: Option<Table>

Used for internal table states.

right_table: Option<Table>

Used for internal table states.

output_indices: Vec<u32>

The output indices of current node

left_deduped_input_pk_indices: Vec<u32>

Left deduped input pk indices. The pk of the left_table and The pk of the left_table is [left_join_key | left_inequality_key | left_deduped_input_pk_indices] left_inequality_key is not used but for forward compatibility.

right_deduped_input_pk_indices: Vec<u32>

Right deduped input pk indices. The pk of the right_table is [right_join_key | right_inequality_key | right_deduped_input_pk_indices] right_inequality_key is not used but for forward compatibility.

null_safe: Vec<bool>

asof_desc: Option<AsOfJoinDesc>

join_encoding_type: i32

Which encoding will be used to encode join rows in operator cache.
