一. 計劃:
TokuDB文檔描述其具備的高insert效能、高壓縮比、hot schema changes等特性較符合日誌類項目的應用情境,耳聽眼見終是虛,實測是必須的。
目前TokuDB僅支援MySQL5.5.x與MariaDB5.5.x,相比較之下Percona的支援要好很多,但仍然需要分開下載進行安裝。此次的測試內容:MySQL5.6.22(innoDB) Vs. TokuDB for Percona5.6.22。

5. 測試小結
1. TokuDB在寫操作(Insert)的表現優於InnoDB,在並發增長的情況下表現亦優於InnoDB。
2. 在此次實際測試中,InnoDB峰值約為11000 per sec,TokuDB峰值約為15000 per sec,並發超過4以後,效能均有不同程度的下降。
3. 在資料壓縮方面,同時產生2千萬行資料,TokuDB表大小約為3.1G,InnoDB表大小約為4.8G。這裡需說明的是測試中TokuDB所啟用的壓縮選項為’fast’,而InnoDB未啟用壓縮。InnoDB也具有壓縮功能,只不過壓縮行為是TokuDB的預設行為。在本文測試中並未使用InnoDB的壓縮格式。
4. 對測試造成的影響的問題因素:1. 共用儲存的IO控制與爭用對測試過程的影響。
