✅ - gen 2 custom mutation for batch write

[untold fiber]

I am searching to find an example or doc to create a custom mutation to save an array of a model. Is there someone who can help me on this?. Let the model be a post and I want number of post to be saved on db

By batch write do you mean calling the BatchWriteIItem DynamoDB operation?

Yes @bleak spoke

I would start by creating a custom mutation following this guide: https://docs.amplify.aws/react/build-a-backend/data/custom-business-logic/

Looks like there are two options, either a custom function where you can call the DynamoDB operation directly, or perhaps a fancier option with a JS appsync resolver.

I have read this and couldn’t find what I aim to create
