![]() ![]() Here's a test done from the API Gateway console:įor a detailed screenshot-guided walkthrough of this entire process, see my blog post. Now you can hit this API with the query param Enabled=true / Enabled=false to enable/disable your Lambda's SQS trigger. Every time the process receives a message it sends it to an SQS queue. Scroll further down & provide this mapping template: Content-Type: application/json Read SQS queue from AWS Lambda Ask Question Asked 7 years, 5 months ago 4 years, 9 months ago Viewed 21k times Part of AWS Collective 13 I have the following infrastructure: I have an EC2 instance with a NodeJS+Express process listening on a port for messages ( process 1 ). The execution role shown above must allow API Gateway to invoke Lambda APIs. The UUID you got above is highlighted below: Next, either create a new API in API Gateway or add a resource & a GET method to your existing API. "StateTransitionReason": "USER_INITIATED" It is set up to trigger from QUEUEA, do some modification of the payload body, then send it to QUEUEB on success, or QUEUEERRORS on failure. Total concurrency is equal to or less than the number of unique MessageGroupIds in the SQS FIFO queue. I have a simple lambda function that is triggered from a SQS queue and Im using the new Lambda Destinations functionality. mircoservices), distributed systems, and serverless applications. Use the AWS CLI to get this (it isn’t shown on the UI): aws lambda list-event-source-mappings -function-name my-func New for AWS Lambda SQS FIFO as an event source: In SQS FIFO queues, using more than one MessageGroupId enables Lambda to scale up and process more items in the queue using a greater concurrency limit. Amazon SQS (Simple Queue Service) is a fully managed message queuing service by AWS that enables you to lower the degree of coupling between services (ex. If, for some reason, you want your own API for this, you can create one in API Gateway as described below.īefore you begin, you need the UUID of the event source mapping you wish to enable/disable. Call Lambda's UpdateEventSourceMapping API with the request body. ![]()
