If you are in a development environment, you can set up a single node Replica Set. Some features like transactions and change streams rely on the oplog collection which only exists in Replica Set. A Replica Set can work with a single primary node. You won't have fail over of course, but it's not the point in a dev environment.

This doc page has been up for as long as I can remember: https://docs.mongodb.com/manual/administration/security-chec.... It's also stated in the production notes: https://docs.mongodb.com/manual/administration/production-no....

It's already implemented actually :') ! Trust me. I'm an engineer :D. https://github.com/mongodb/mongo/blob/72ed8227aa029afd554aa5...

That was true with MMAPv1. It's not since March 2015, when WiredTiger was introduced with MongoDB 3.0.

MongoDB supports Schema Validation since MongoDB 3.2 (Dec. 2015) and JSON Schema since MongoDB 3.6 (Nov. 2017) so MongoDB can enforce types strictly if you want to at the collection level. NoSQL doesn't mean NoSchema or NoTypes. https://docs.mongodb.com/manual/core/schema-validation/#json...

Hi, I also built a dashboard using MongoDB Atlas and MongoDB Charts. Here is my blog post about it: https://www.mongodb.com/blog/post/tracking-coronavirus-news-.... You can find my data import script in my Github in the blog post. I also gave more details in a comment and another blog post in on the way around this topic. Feel free to use it to feed your MongoDB collection with fresh data :-).

The best place to learn about MongoDB is the MongoDB free e-learning university website: https://university.mongodb.com. You can follow free courses here - MOOC style.
