Sending 500 requests parallely in awa appsync results error

Is this the request token error?

The error with status code 429 you encountered when sending 500 parallel requests to AWS AppSync is due to exceeding the API rate limits, which prevents excessive resource consumption. This is a common throttling response for managing data traffic and ensuring service stability.

AWS documentation doesn't provide a direct solution for the 429 error, but it outlines common issues that might help you diagnose and mitigate similar problems. Ensuring correct request mapping, resolver configurations, and return types can improve API performance and reduce unnecessary calls, which might indirectly help with throttling issues by reducing overall load

To handle this:

1. Review AppSync's current rate limits for your account and consider requesting an increase if necessary.
2. Implement exponential backoff and retry mechanisms in your code to better handle rate limiting.
3. Optimize your application's data fetching strategies to reduce the number of necessary requests.
