[jira] [Created] (ARROW-12892) [C++][Dataset] Remove Dataset::partition_expression

Ben Kietzman created ARROW-12892:
------------------------------------

             Summary: [C++][Dataset] Remove Dataset::partition_expression
                 Key: ARROW-12892
                 URL: https://issues.apache.org/jira/browse/ARROW-12892
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Ben Kietzman


We don't have compelling use cases for this and now that subtree pruning has been restored in ARROW-8658 it offers no performance advantage over attaching the common expression to each of the Dataset's Fragments.
