datax json

錢良釵1年前7瀏覽0評論

datax是一種數(shù)據(jù)同步工具,可以將不同數(shù)據(jù)源之間的數(shù)據(jù)進(jìn)行同步,而在實際應(yīng)用中,我們通常需要將數(shù)據(jù)進(jìn)行轉(zhuǎn)換和映射處理,此時datax的json插件就顯得尤為重要了。

"column": ["id", "name", "age"],

上述代碼片段展示了一個簡單的datax job配置,包括了mysqlreader作為數(shù)據(jù)讀取源,regex作為數(shù)據(jù)轉(zhuǎn)換模塊,mysqlwriter作為數(shù)據(jù)寫入目地。json格式使得配置更加清晰易懂,并且datax針對不同的數(shù)據(jù)源和轉(zhuǎn)換模塊都提供了豐富的json配置選項。
