Mike Seddon created ARROW-10819:
-----------------------------------

             Summary: [Rust] [DataFusion] Implement EXISTS operator
                 Key: ARROW-10819
                 URL: https://issues.apache.org/jira/browse/ARROW-10819
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Rust - DataFusion
            Reporter: Mike Seddon


The TPC-H queries include use of the EXISTS which is used to test for the existence of any record in a subquery. For example:

and *exists* (
    select
        *
    from
        lineitem
    where
        l_orderkey = o_orderkey
        and l_commitdate < l_receiptdate
)
