## Comments

04/Mar/25 09:07;codope;We have over 25+ tests across table types and many operations in `TestExpressionIndex` and `TestHoodieIndexer`. Following write operations need to be covered:
* insert_overwrite
* insert_overwrite_partition
* delete_partition
* restore (though rollbacks are covered);;;
