### Proposed Change Here is the motivation of the proposal and the detail can be found in the proposal document. **Motivation** I'm working on the Incremental Materialized View based on Spark + Iceberg. CDC of the Iceberg table is very important for such a feature. Currently, position delete is used for the Delete/Update command and CDC of delete info can't be got from delete file directly. Change Log may be the only way to get the difference between 2 snapshots. But it needs to be generated first and better to identify primary keys for better performance. RowId is introduced in V3 format and designed as the unique key for every row. If RowId can be used for deleted rows, then getting CDC of delete info will be more convenient. ### Proposal document https://docs.google.com/document/d/19XiF4dAtlr19lC6-myGog9zqzcjgrJqngdTvOx5yOVA/edit?usp=sharing ### Specifications - [x] Table - [ ] View - [ ] REST - [ ] Puffin - [ ] Encryption - [ ] Other -- This is an automated message from the Apache Git Service.
