Description

w/ RLI, we are introducing a proper way to delete a MDT record. [https://github.com/apache/hudi/pull/9058] 

 

We might have to follow similar logic for other partitions as well to optimize it better. We should avoid relying on nested fields to deduce whether a record is deleted (for eg, 

ColumnStatsMetadata.isDeleted

Research direction

Start by reading the linked RLI pull request and tracing the MDT deletion paths for column statistics and bloom-filter partitions. Inspect how ColumnStatsMetadata.isDeleted is used; done means relevant partitions use proper entire-record deletion rather than inferring deletion from nested fields.
