-------------------------------
Resolution: Invalid
> [Rust][DataFusion] switching key join order results in error
> ------------------------------------------------------------
>
> Key: ARROW-10965
> URL: https://issues.apache.org/jira/browse/ARROW-10965
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust - DataFusion
> Reporter: Daniël Heres
> Priority: Minor
>
> If we switch the order of keys in a equijoin this results in an error. It
> seems that some code assumes that the left key in the expression is in the
> left input of the join and the right key comes from the right side.
> For example changing l_orderkey = o_orderkey to
> o_orderkey = l_orderkey
> in query 12 of the tpch benchmark, we get this error:
>
> {{Error: Plan("The left or right side of the join does not have all columns
> on \"on\": \nMissing on the left: \{\"o_orderkey\"}\nMissing on the right:
> \{\"l_orderkey\"}")}}
