zanmato1984 opened a new issue, #45135: URL: https://github.com/apache/arrow/issues/45135
### Describe the enhancement requested There exists a member in `HashJoinNode` identifying wether the hash table is built so we can proceed with probe https://github.com/apache/arrow/blob/1e45e182a71d51223cfb82b236dde07b436f44f1/cpp/src/arrow/acero/hash_join_node.cc#L1039 So the following two states in `SwissJoin`: https://github.com/apache/arrow/blob/1e45e182a71d51223cfb82b236dde07b436f44f1/cpp/src/arrow/acero/swiss_join.cc#L2930 https://github.com/apache/arrow/blob/1e45e182a71d51223cfb82b236dde07b436f44f1/cpp/src/arrow/acero/swiss_join.cc#L2913 are useless. We can also tell it from the fact that they are all written but never read (except for a `DCHECK` which is also unnecessary). ### Component(s) C++ -- This is an automated message from the Apache Git Service.
