Description

Currently HiveIcebergStorageHandler prevents proceeding to vectorized reading code path for V2 Iceberg tables, as the feature for reading in delete information and merging this to VectorizedRowBatches is missing.

This should serve as an umbrella jira to implement the feature.

• Populate file row position information during vectorized Iceberg reads: Closed
• Implement row iterator for VectorizedRowBatch: Closed
• Create vectorized Hive DeleteFilter for Iceberg tables: Closed
• Support vectorized read with Iceberg equality deletes: Open
