MongoDB has announced updates to Atlas Stream Processing, including support for eight new AWS regions across the US, Europe, and APAC, enhancing deployment flexibility. The platform now supports VPC peering for self-hosted Apache Kafka on AWS and Amazon Managed Streaming for Apache Kafka (AWS MSK), providing a secure method for connecting between virtual private clouds. Atlas Stream Processing has also expanded support for Apache Kafka, allowing developers to read and write Kafka keys on their events. Additionally, the platform now supports creating and deleting stream processors, as well as fetching operational stats of stream processors using the Atlas Admin API. These updates aim to make it easier for developers to integrate stream processing into their applications.
