### Describe the bug Seen / discussed in: https://github.com/apache/datafusion/pull/19639 https://github.com/apache/datafusion/issues/3463 We need to nail down what is slow: 1. Creating the expressions? 2. Evaluating them? If (2), what's the solution? - Is our approach to filter pushdown fundamentally flawed because it changes the parallelism or batch sizes at which the filter is applied? Could we do something to make the expression more efficient, like put the min/max evaluation outside of the hashes? - Is it just because the hashes are being evaluated more times? - Is it less of a problem on a larger dataset? ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
