Light-City opened a new pull request, #37398: URL: https://github.com/apache/arrow/pull/37398
### Rationale for this change we add a node for acero, which also called nested loop join. At present, acero lacks a nested loop join node. We completely implement the nested loop join that can run tpch and tpcds according to the implementation method of hashjoin. Currently, the following join types are supported. INNER、LEFT_OUTER、LEFT_SEMI、LEFT_ANTI. The NestedLoopJoin implementation is based on the HashJoin Basic implementation, constructing the match, no_match, match_left, and match_right arrays, and then output each batch. In the future, we will support more join types and parallelization ### What changes are included in this PR? - nestedloop node - nestedloop implement - nestedloop test ### Are these changes tested? add cpp/src/arrow/acero/nested_loop_join.cc add cpp/src/arrow/acero/nested_loop_join.h add cpp/src/arrow/acero/nested_loop_node.cc add cpp/src/arrow/acero/nested_loop_node.h add cpp/src/arrow/acero/nested_loop_node_test.cc ### Are there any user-facing changes? yes, tpch or tpcds include nested loop join plan. -- This is an automated message from the Apache Git Service.
