[GitHub] [arrow-datafusion] Dandandan opened a new issue, #5149: Unecessary `Filter` on Parquet datasources
Dandandan opened a new issue, #5149:
URL: https://github.com/apache/arrow-datafusion/issues/5149
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Now that Parquet supports pushing down predicates to the scanning phase, we could remove the additional filter, as we're no longer providing an inexact filter.
**Describe the solution you'd like**
Add a method to `FileFormat` that returns whether the format supports exact filter pushdown.
The `supports_filter_pushdown` function should be updated accordingly.
**Describe alternatives you've considered**
**Additional context**
