Work Description: pvary opened a new pull request #2137:
URL: https://github.com/apache/hive/pull/2137
### What changes were proposed in this pull request?
There are 3 parts of the changes here:
- Pruner changes to provide a filter instead of changing the file lists
- HiveInputFormat changes to combine the Pruning filter with the original
filter
- Iceberg handler changes:
- New method in SerDe to return the current partitioning columns
- HiveStoragePredicateHandler implements the addDynamicSplitPruningEdge
method which returns true if there is a filter for any of the partitioning
columns
- Added new test for partition pruning
### Why are the changes needed?
To archive comparable performance for Iceberg tables
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Multiple queries
Plan to add more tests later, but it would be good to have them as a `qtest`
and it should be done in a different PR as it is a sizable task in itself
