AWS Database Migration Service now supports automatic segmentation using MongoDB and Amazon DocumentDB (with MongoDB compatibility) as a source

AWS Database Migration Service (AWS DMS) expands functionality by supporting automatic segmentation using MongoDB and Amazon DocumentDB (with MongoDB compatibility) as a source. Using AWS DMS, you can configure DMS tasks to segment the collection of a MongoDB cluster automatically and migrate them in parallel to any AWS DMS supported target including Amazon DocumentDB (with MongoDB compatibility) with minimal downtime.
