一、query语句，制定数据同步规则。

 

 

同步2021-07-05一天的数据

"{'createTime':{'$gt':NumberLong('1625414400000'),'$lt':NumberLong('1625500800000')}}"

二、

您可以通过该配置型来限制返回MongoDB数据范围，仅支持时间类型。例如您可以配置
"query":"{'operationTime':{'$gte':ISODate('${last_day}T00:00:00.424+0800')}}"，限制返回operationTime大于等于${last_day}零点的数据。此处${last_day}为DataWorks调度参数，其中
last_day格式为
yyyy-mm-dd。您可以根据需要具体使用其它MongoDB支持的条件操作符号（$gt、$lt、$gte和$lte等），逻辑操作符（and和or等），函数（max、min、sum、avg和ISODate等）。

三、

同步json脚本
