[GitHub] [flink-table-store] JingsongLi commented on pull request #199: [FLINK-28159] Table Store: Bucket pruning based on bucket key filter

JingsongLi commented on PR #199:
URL: https://github.com/apache/flink-table-store/pull/199#issuecomment-1175889238

   > I'd like to hide bucket keys from `FileStore`. We should handle them only in `FileStoreTable` so that `FileStoreScan` only needs to know the indices of the buckets to scan.
   
   I think bucket is a concept that FileStore already perceives
   - `KeyValueFileStoreScan` is only used to know that the bucket key must be in the key (it only senses Key and Value)
   - `AppendOnlyFileStoreScan` only needs to know that the bucket key must be in the Row
   
   Previously, we also discussed the concept of putting bucket writers' maintenance in the FileStore, theoretically Table level just wrap Row.
