如何处理与AWS AppSync脱机同步的数据? [英] How to handle data offline Sync with AWS AppSync?

问题描述

我已经将IOS应用程序设置为DataSource作为"HTTP端点". 我可以获取所有用户并自动存储在mysqli DB中，并且该数据可脱机使用. 我还尝试了对突变的订阅，它也可以正常工作.

I have set up an IOS app with DataSource as "HTTP endpoint". I can fetch all users and auto store in mysqli DB and this data is available offline. I have also tried the subscriptions to mutations which also works fine.

现在我的问题是如何同步数据.假设我有10行，当我离线时有2个新行可用.我怎么知道这些可用?

Now my question is how do I sync the data. suppose I have 10 rows and there is 2 new row available when I was offline. how do I know these are available?
