GitHub user severinson edited a discussion: Does Acero support multi-column joins?
Hey. I’m trying to use Acero to join two Arrow tables on multiple columns. I’ve created a Substrait plan for doing so containing an and expression with one equals expression per pair of columns. However, I get the error ”Only equal or is_not_distinct_from are supported for join key”. Is there a way to produce a Substrait plan that would do such a join? Joining on one column works since I can then use an equals expression directly.
