MongoDB & Node.js: Aggregation & Data Analysis (Part 2 of 4)

Exactly what I was looking for!

You explain everything so fantastically

Geate vdos

Thanks! Then, if you want to put that data in an HTML table, how do you do it?

How pipeline works in background? Does all calculation are done on DB side? Is it works like a stream or pipeline is transformed to standard query?

Thank you very much. I leaned a lot.

How to restart a change stream after dropping a collection?

DAMN you really helped me on my MSc project !!!!!!! amazing

thanks!! I have a collection with 1MM and $group is very low in pipeline, can you send me a example for this usecase?

And yo', thanks for the amazing explanation, minimal but delivers.

For a dev leaning towards the JAMStack, this right here is a big deal. I just write few lines of code on my end and MongoDB Cloud takes care of the rest. Hakuna Matata. Thank you.

Great content!
I hope you're going to explain in 4th ( change streams etc.) how to execute them in Realm, because I can't find a working complete code and I always got my (database) triggers suspended (trying to run aggregation pipeline and saving result to another collection).
Also, being able to export such a working code (for Realm functions, for scheduled and database triggers) while exporting pipeline to text would be a great feature!
I can't wait for 4th! :)

How do I access my virtual properties in an aggregate query?

Can you teach us please how to use singleton with nodejs ? Thank you so much for content :D

Love the first part, from the explanation, minimalism, everything, this series was looking forward to part 2 and the best thing is that I was just reading and watching videos to improve and understand even more mongoDB than I knew and I fell like ring to finger this video series.

Thanks for the work Lauren and the Mongo team

Thank you for your illustration, can we install aggregation framework locally on our own server?
