If your data is stored in existing relational databases, converting relational data structures to documents can be complex and involve constructing and managing custom extract, transform, and load (ETL) pipelines. Amazon Database Migration Service (AWS DMS) can manage the migration process efficiently and repeatably. With AWS DMS, you can perform minimal downtime migrations, and can replicate ongoing changes to keep sources and targets in sync. This post provides an overview on how you can migrate your relational databases like MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and others to Amazon DocumentDB using AWS DMS.

With the launch of MongoDB 4.0 compatibility, Amazon DocumentDB (with MongoDB compatibility) now supports performing transactions across multiple documents, statements, collections, and databases. Transactions simplify application development by enabling you to perform atomic, consistent, isolated, and durable (ACID) operations across one or more documents within an Amazon DocumentDB cluster. Common use cases for transactions include financial processes, fulfilling and managing orders, and building multi-player games. In this post, I show you how to use transactions for common uses cases.
