AWS AppSync Resolvers Timeout When Fetching Data from DynamoDB with VTL
I'm trying to implement I'm deploying to production and I'm trying to configure I'm experiencing a timeout scenario with my AWS AppSync GraphQL API when trying to fetch data from DynamoDB using VTL (Velocity Template Language) resolvers..... My API call takes too long and eventually returns a 504 Gateway Timeout behavior. I've set up my DynamoDB table to handle requests efficiently, with read capacity units far exceeding my load, but it seems like the resolver isn't executing in a timely manner. Here's the resolver mapping template I'm using: ```vtl #set($pk = $ctx.args.id) #getItem ( { "TableName": "MyTable", "Key": { "id": { "S": "$pk" } } } ) ``` In my AppSync configuration, I'm using a default timeout of 5 seconds for the data source, which I suspect may be too short. I've also checked the CloudWatch logs, and the DynamoDB read requests are returning results quickly. Still, the overall resolver is timing out. I've tried increasing the timeout in the AppSync console to 10 seconds, but the timeout continues. Additionally, I've looked into increasing the DynamoDB read capacity temporarily to see if it makes a difference but haven't seen any improvements. Could this be related to how the resolver is structured, or is there something else in the AppSync configuration I should be checking? Any suggestions on optimizing the VTL mapping or diagnosing this scenario further would be greatly appreciated!
