MICROSOFT BUILDS OPEN SOURCE DOCUMENT DATABASE ON POSTGRESQL, SUGGESTS FERRETDB AS FRONT END

Summary from the TLDR newsletter

Developers looking to build something new on a document database now have more alternatives to choose from. Microsoft has launched a document database platform constructed on a relational PostgreSQL back end. It has suggested that users kick things off by implementing a FerretDB solution on the platform to get started. Microsoft has been increasingly accepting of the open source world. The joint development between Microsoft, PostgreSQL, and FerretDB is a threat to source-available MongoDB and Couchbase.
