Change Streams in MongoDB 6.0 Support Pre- and Post-Image Retrieval, DDL operations, and more

MongoDB 6.0 introduces new functionality to its Change Streams API, allowing for pre- and post-image retrieval, support for data definition language (DDL) operations such as creating and dropping indexes and collections, and improved performance with filtering stages pushed to optimal positions within change stream pipelines. These enhancements expand the use cases that Change Streams can address, enabling teams to build event-driven applications or systems on MongoDB that capture and react to data changes in near real-time, without requiring middleware or database polling scripts.
