rdblue opened a new pull request, #4947: URL: https://github.com/apache/iceberg/pull/4947
This adds `ExpressionUtil.equivalent` and `ExpressionUtil.selectsPartitions` to determine whether an expression will select whole files in a partition spec. This is needed to determine whether a filter is guaranteed to delete only whole files, or whether a row-level plan should be used. It is also needed to implement aggregate pushdown with non-trivial filters because filters must match whole files in order to use file metadata to satisfy a query. -- This is an automated message from the Apache Git Service.
