Question :

I have a question about graphql queries on react js app

when i was using AppSync to test some data, i just noticed there is a column called _version which is related to Conflict Resolution on the react side i'm using API.graphQL funciton to CRUD operations but that _version column makes things harder so : 1- can i turn off this Conflict Resolution? 2- how should handle this versioning stuff? 3- should i only use AppSync for Managing Data ? 4- when i remove data using API.graphQL it is still there! what should i do? also i tried DataStore too and that is offline first library but in my application i need to be fully online i dont want to save data temporarily on client-side and then upload when it gets online also there is no way to log the result to detect that a record has been saved locally or online!

so Datastore questions: 1- how should i get the result log of an operation? 2- how to turn off offline-first ability?

Hello @sina-developer Conflict Resolution is a AppSync Feature which is used as a part of DataStore. For info on what the fields (such as _version) mean refer to the AppSync dos below. You can check if you have this enabled if there is a ResolverConfig in your transform.conf.json. If you have this enabled it is best to use the DataStore library as the deleting a field will leave it with a timestamp when the said record will expire. (mentioned in the appsync docs). If you would not like to use datastore you can disable it when running amplify update api.

If you have any issues/questions using DataStore from the library. I'd recommend opening a question/discussion thread with the amplify library you are using.
