请教一个APP端与服务端同步数据的思路
我当前有这样一个需求，APP端需要展示一个记录列表，记录的数量每天都会增加，同时历史记录的状态也可能改变。用户登录时需要与服务端同步数据，我现在的思路是这样的：
1、保存记录在数据库里的自增_id，根据此_id 来取新数据；
2、APP端记录一个最后更新的时间戳，服务端每条记录都保存最后更新时间戳，请求的时候比对时间戳，只取该时间戳后变更的数据。
备注：数据库是Mongodb。
不知道该思路是否OK，或者有更好的方案？谢谢！

数据库里要有update_time和create_time,你请求的时候，传本地数据库中update_time和create_time中最大的值就行了。这应该就是所谓的增量更新方式
时间戳是个不错的解决方案
