nealrichardson opened a new pull request, #41372: URL: https://github.com/apache/arrow/pull/41372
### Rationale for this change Noticed in #41350, I made #41358 to implement this in C++, but it turns out the option was there, just buried a bit. ### What changes are included in this PR? `na_matches` is mapped through to the `key_cmp` field in `HashJoinNodeOptions`. Acero supports having a different value for this for each of the join keys, but dplyr does not, so I kept it constant for all key columns to match the dplyr behavior. ### Are these changes tested? Yes ### Are there any user-facing changes? Yes -- This is an automated message from the Apache Git Service.
