Answer / Nand Kishor Jha
"Soft Deletes": These are records that have been marked as deleted but still exist on the table. They are replaced with a special marker called 'tombstone' and are recoverable until they are overwritten or their time-to-live expires.nn"Hard Deletes": These are records that have been completely removed from the table and cannot be recovered unless a backup is available.nn"Visible Tombstones": These occur when a new version of a row with the same key is written before an earlier version's time-to-live expires, making the older version 'visible' as a tombstone.
