Description
KeyDeletingService, iterate several records from scratch each time, send deletion requests, and then delete these records.
If each iteration starts from scratch, Rocksdb will also include the recently deleted tombstone data in the scan.
The optimization is to optimize the iteration strategy, record breakpoints for each iteration, skip known tombstones, and reset breakpoints if errors occur during the iteration or if the endpoint is reached.
