移動端orm框架性能測評

flutter_orm_plugin 發佈以來，很多團隊試用了，我發現你們對這類數據庫相關的庫，第一反應就是性能如何，以前確實沒作太多行業對比，最近以爲仍是有必要作一下性能測試，給你們一個交代的。java

在ios端，業界比較經常使用的orm框架應該是蘋果官方推出的coredata，還有就是realm了。在android端orm框架我挑了三個比較經常使用的，greendao，realm和activeandroid。我會用flutter_orm_plugin跟上面提到的ios和android端orm框架作對比。 下面我會分別給出測試用例，測試代碼，還有最終數據比較的結果。android

測試用例

測試用例我列了如下這些ios

  • 10000次插入數據
  • 使用批量接口10000次插入數據
  • 10000次讀取數據
  • 10000次修改數據
  • 使用批量接口10000次修改數據
  • 10000次刪除數據
  • 使用批量接口10000次刪除數據

爲何會有普通插入數據和使用批量接口插入數據的區別，大部分orm框架都會對批量操做有必定的優化，因此須要對批量操做進行測試，可是在平時使用，不必定都能用上批量接口（例如屢次數據操做不在同一代碼塊，或者在不一樣的模塊中都要操做數據），因此咱們會分別對普通操做和批量操做進行測試。git

android 測試代碼

首先咱們給出flutter_orm_plugin 的測試代碼，因爲不想由於flutter和原生channel通信產生偏差，咱們直接用Luakit來寫lua代碼作測試（greendao、realm、activeandroid、coredata都不涉及flutter和原生channel通信），flutter_orm_plugin其實底層就是luakit的orm框架，這個不影響測試準確性。github

  • 能夠看到，active android各項性能都通常。

  • 在使用批量接口的狀況下GreenDao和Realm的性能比較好。

  • 在使用批量接口的狀況下Realm的性能尤爲好，批量插入、查詢、批量更改、批量刪除都是Realm的性能最好，可是Realm的非批量接口性能較差，全部能夠這樣總結，若是代碼高內聚，能夠把數據操做代碼入口都統一使用，Realm性能是最好的，但這對代碼質量、模塊設計有要求，當操做數據的代碼處處都有，不能使用批量接口時，Realm的性能是很差的。

  • Luakit沒有提供批量接口，但從圖中能夠看出，Luakit的各項性能指標都是比較好的，並且對代碼沒有要求，即便操做數據的代碼不內聚，也不會對性能有影響。

  • 能夠看到，Coredata除了批量插入性能是最好的之外，其餘項性能都通常。

  • Realm ios和Realm android性能很是類似，批量操做性能優異，可是非批量操做性能通常。能夠這樣總結，若是代碼高內聚，能夠把數據操做代碼入口都統一使用，Realm性能是最好的，但這對代碼質量、模塊設計有要求，當操做數據的代碼處處都有，不能使用批量接口時，Realm的性能是很差的。

  • Luakit沒有提供批量接口，但從圖中能夠看出，Luakit的各項性能指標都是比較好的，並且對代碼沒有要求，即便操做數據的代碼不內聚，也不會對性能有影響。
