该文测试的环境以下

CPU details (Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz with 72 CPUs)

Storage devices used for benchmarking (we used NVME SSD)

MySQL (we have used Percona Server 5.7.22-22 with InnoDB/XtraDB, TokuDB and RocksDB) configuration / system variables 

 

测试结果下面提供简单的各环节结果及最终结论，各个库的配置参数等详情在原文中也有。

Graphical representation of  OLTP INSERT performance in TokuDB, RocksDB and InnoDB: 

 

Graphical representation of  OLTP READ-ONLY transactions performance in TokuDB, RocksDB and InnoDB: 

 

Graphical representation of  OLTP READ-WRITE transactions performance in TokuDB, RocksDB and InnoDB:

The results of benchmarking concluded RocksDB the most ideal candidate for SSD based storage infrastructure compared to InnoDB and TokuDB, The most compelling reasons for using RocksDB on SSD are performance, storage efficiency/compression and much smaller write amplification compared to InnoDB or TokuDB.
