> @liming30 Thanks for your PR. Would you like to share some improvements if this PR merged via [flink-benchmarks](https://github.com/apache/flink-benchmarks). Hi, @fredia, I wrote the following benchmark on my local Mac and ran the JMH test. `deleteRange` is almost 10 times faster than `Iterator`. ``` @Benchmark public void mapClear(KeyValue keyValue) throws Exception { keyedStateBackend.setCurrentKey(keyValue.setUpKey); mapState.clear(); } ``` Performance test results using `Iterator`: ``` Benchmark (backendType) Mode Cnt Score Error Units MapStateBenchmark.mapClear ROCKSDB thrpt 30 13.165 ± 2.088 ops/ms ``` Performance test results using `deleteRange`: ``` Benchmark (backendType) Mode Cnt Score Error Units MapStateBenchmark.mapClear ROCKSDB thrpt 30 121.860 ± 16.605 ops/ms ``` -- This is an automated message from the Apache Git Service.
