該文測試的環境如下

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 

 

測試結果下面提供簡單的各環節結果及最終結論，各個庫的配置參數等詳情在原文中也有。

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.
