-----------------------------------------
Summary: [Python] Support Expressions in `Table.filter`
Key: ARROW-16279
URL: https://issues.apache.org/jira/browse/ARROW-16279
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Alessandro Molina
Assignee: Alessandro Molina
Fix For: 9.0.0
*Umbrella ticket*
At the moment {{Table.filter}} only accepts a mask, and building a mask that
actually leads to the rows we care about can be complex and slow in cases where
more than one compute function is used to generate the mask. It would be
helpful to be able to pass an {{Expression}} as the argument and get the table
filtered by that expression as expressions are easier to understand and reason
about than masks.
