[jira] [Created] (ARROW-10965) [Rust][DataFusion] switching key join order leads to error

Daniël Heres created ARROW-10965:
------------------------------------

             Summary: [Rust][DataFusion] switching key join order leads to 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


If we switch the order of keys in a equijoin this results in an error.

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\"}")}}
