Amazon SQS has many advantages: Decoupled: SQS makes it easy to decouple and scale microservices, distributed. In lambda scroll down click on monitor-view Cloudwatch logs where we can see Message, attributes. A mazon Simple Queue Service (SQS) is a fully managed message queuing service. SQS send message and trigger lambda function we will check logs in Cloudwatch Assuring the idempotency of your processing. Relying on a batch size of “1”, which makes messages either succeed or fail one on their own. Iam Role : Permission-AWSLambdaSQSQueueExecutionRoleĪWSLambdaSQSQueueExecutionRole policy has the permission that function needs to read items from Amazon SQS and write logs to Cloudwatch.Ĭreate Policy choose service name SQS then defining actions with applying resources.Īdd the Amazon resource name( ARN) of SQS- Copy ARN from SQS as attached below.Ĭreate a Lambda Function that processed Amazon SQS messages using here python code.Īdd Trigger on lambda function drop down SQS queueīatch size – Maximum number of SQS message to be sent to the lambda function every time a single trigger is set. Step to Step Integration of SQS with AWS Lambda: Message that are successfully processed are removed from queue and failed message are forwarded to DLQ(Death letter queue). Sometimes need to retry only a specific number of times, and if can’t process it, remove it from the source queue automatically. Lambda automatically tasks like polling, reading and removing message from a queue. Lambda Functions are automatically triggered when messages arrive to an SQS Queue. Lambda-It is compute service that lets you run code without provisioning or managing servers. SQS include metadata(timestamps, geospatial, data, signatures and identifiers) Without having to deal with decoupled component overhead of creating & maintaining message queue. Where one service sends message in queue & another service receives those message. The small lambda function which will work as data shipper that pulling data from sqs and push to Elasticsearch.Lambda first check index existence if it is found. SQS-It is fully Managed Message Queue service. First let's know a Little about it what SQS and Lambda are?
