Kneel down: MongoDB Advanced Material Recommendation

  mongodb, question

Recently, I studied MongoDB and found some materials and books on the internet. I found that most of them are basic and not too deep.

Especially, the use of MapReduce and Aggregation Pipeline is even less.

As for MongoDB’s strong query support, it is still unclear where it is embodied.
