You can use Yahoo! Cloud Serving Benchmark (YCSB) to test persistent memory-optimized instances of ApsaraDB for Redis Enhanced Edition (Tair). This topic describes the test tool and how to use it.

You can use open source YCSB to perform stress tests. YCSB is a Java tool that can be used to benchmark the performance of multiple types of databases. For more information about how to install and use YCSB, see YCSB.

Open source YCSB tests only hashes. To use YCSB to test strings, you must use the RedisClient.java file to replace the original file that has the same name in the YCSB/redis/src/main/java/site/ycsb/db directory after you download YCSB.
