§join_type: i32§left_key: Vec<i32>§right_key: Vec<i32>§condition: Option<ExprNode>§inequality_pairs: Vec<InequalityPair>§left_table: Option<Table>Used for internal table states.
right_table: Option<Table>Used for internal table states.
left_degree_table: Option<Table>Used for internal table states.
right_degree_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 left_degree_table is [left_join_key | left_deduped_input_pk_indices] and is expected to be the shortest key which starts with the join key and satisfies unique constrain.
right_deduped_input_pk_indices: Vec<u32>Right deduped input pk indices. The pk of the right_table and right_degree_table is [right_join_key | right_deduped_input_pk_indices] and is expected to be the shortest key which starts with the join key and satisfies unique constrain.
null_safe: Vec<bool>§is_append_only: boolWhether to optimize for append only stream. It is true when the input is append-only
