ming li commented on FLINK-28010:
---------------------------------

[~Yanfei Lei] thank you for your reply, I think this can save us a lot of 
delete overhead. At the same time, can this also optimize the performance of 
seek? Because LSM-Tree is not friendly to range-query when there are a large 
number of tombones.

> Use deleteRange to optimize the clear operation of RocksDBMapState.
