I would like to discuss about new mangodb.
Official documents says about
MangoDB is set out to become the de-facto open-source alternative to MongoDB. MangoDB is an open-source proxy, which converts MongoDB wire protocol queries to SQL, and uses PostgreSQL as a database engine.
Why do we need MangoDB?
MongoDB is a life-changing technology for many developers, empowering them to build applications faster than using relational databases. Its easy-to-use and well-documented drivers make MongoDB one of the easiest to use database solutions available. However, MongoDB abandoned its open-source roots, changing the license to SSPL - making it unusable for many open source and commercial projects.
Most MongoDB users are not in need of many of the advanced features offered by MongoDB; however, they are in need of an open-source database solution. Recognizing this, MangoDB is here to fill the gap by providing an alternative.
You can use docker too:
docker run --rm -it --network=mangodb_default --entrypoint=mongosh mongo:5 mongodb://mangodb/
Visit at www.mangodb.io, get in touch, and sign up for updates on the project.
