AWS Lambda now supports content filtering options for Amazon MSK, Self-Managed Kafka, Amazon MQ for Apache ActiveMQ, and Amazon MQ for RabbitMQ. With event pattern content filtering, customers can write complex rules so that their Lambda function is only invoked to process meaningful events. This helps reduce traffic to customers’ Lambda functions, simplifies code, and reduces overall cost. Filtering was already available for SQS, DynamoDB, and Kinesis as event sources for Lambda.
