Try MongoDB Atlas, our fully-managed database as a service. Let's take a look at some things to consider. MongoDB is designed to take care of many performance aspects by itself but it leaves to designers and developers to figure out the best possible data model for the specific application patterns. The problem is that the most of them don't focus on MongoDB schema design patterns. When that occurs we can create and save the new schema to the database with a schema_version field. Introduction Name derived from humongous (= … We can assume that doc… The Bucket Design pattern works great for many cases.
