Execution Timeout AWS AppSync API

Question

We have an AppSync API in which one of queries is timing out after 30s.  The data source is a lambda which is  taking approximately 70s to complete the execution. The execution of lambda is perfectly fine but we are not able to optimize it under 30seconds. Is there a way to configure this timeout to a minute in AppSync from the backend or the amplify(angular) client from front-end ?

Answer

Hi,

Appsync has a 30 second hard limit for request execution time for mutations, queries, and subscriptions. Please refer to the [Appsync documentation](https://docs.aws.amazon.com/general/latest/gr/appsync.html#limits_appsync) for this limit. Unfortunately, this means that there is no configuration or setting which will allow us to exceed this limit.

If you have a query that is taking more than 30 seconds, then the workaround is to implement this in an asynchronous manner. Please refer to this blog for a strategy in [Implementing a long-running query on AWS AppSync](https://aws.amazon.com/blogs/mobile/invoke-aws-services-directly-from-aws-appsync/)
