Aggregation | MongoDB | Tutorial 10 

This has to got to be one of the best tutorials on aggregation I have ever found. I have been researching aggregation for days for my project, looking up a million references and examples, and I could not understand any of it. Thanks, Mike!

Awesome! Thanks for the short and sweet tutorial Giraffe Academy team!!

Hey Mike, I have referred to your video so many times to refresh my knowledge on aggregation. I would be grateful to you if you could make an advanced MongoDB tutorial series focusing on complex queries using aggregation! There's barely anyone teaching those! Maybe It's too much to ask for 😂 but I haven't seen a better MongoDB teacher than you!

Wonderful job! Keep up the good work! You are an excellent teacher.

Great little video; I'm just starting with Mongo and trying to adapt from PL/SQL. This helped me understand how aggregation syntax is structured.

This so helpful, I was so struggling and searching over internet. But here its so easily explained !!

every single minute of your videos is golden. thanks

As I beginner I started learning code watching your videos Now I have been coding for a year and I would say your videos are very easy to understand thankyou!

This is really, very helpful for the beginners. Thanks Mike

just got to the 10th part and I'm very happy to see Mike introducing himself one more time, hehe, yes, go Giraffe Academy! This is the best I finally got MongoDB

I just saw your video on the list and I am so happy that I watch this. I learn something new today, 5 years old video still very helpful!

This is something I was looking for a long time. Such nice tutorials. Btw, I see a small error in the source code you have provided. You missed a coma on the 6th line and there is an extra comma on 7th.

cool video :)

Good to create a Dashboard, thank you.

thank you big handed king! the videos from the mongodb university are boring as hell. this is fantastic

What if we want to get the sum of values ( including both negative and positive ) along with the negative sign

nice and well explanation :)

Great tutorial, thanks. Ok I understand all of this and I have it working on my computer. Now I need to know how to use all of these commands from within my web app. Is there a way to do this outside of (= without having to learn) MERN/MEAN?

nice video and need more videos on aggregation using $redact and $cond

More tutorial needed on mongo complex things. What about batch processing? What about partial word search? What about transactions? What about views, how you have it in SQL? What about bested documents, reference document fetching? What about count of result? Etc.

Awesome 👍😁

2:30 count is Deprecated, use countDocuments

thanks !

When i saw "Karen": please insert a boolean "complaint" yes or no :> Thanks for the vid !

thanks mike

I wonder what the performance is like compared to processing the data with JS, such as .reduce

Thank you bro

I don't understand english but it was very descriptive congratulations I used google translate to send this message

Hi there, so how would we now connect to our mongo database from our web app - do you cover this in another course?

is aggregation something I can run for normal requests? if I have a user who has many Posts, can I show them their post count using aggregation or is that going to be too slow for production? or say we have a Topic Board, with many threads, can I use aggregation to find the unique posters in that entire board and display that to my visitors, or is this something I should accomplish with javascript on the back end?

Please create tutorial on more advance feature like replica set, mongodb server deployment, and improvement or optimization in query.

Braaaaaaaaaaaavooooooooooooooo

Is there any way we can reverse the array of objects without the use of field id?

Like

2 hours ago mongodb was just a techbuzz word!

Can we use distinct inside the aggregation? Or would it work if i use distinct first and after i call the aggregation?

I bet Karen asked to see the manager when she bought that Pizza

are the fields indexed? i.e. how quick will the search be?

Why am I getting an error that says i"m missing a : after property id when I follow this?

Nice playlist

How could I get Top 20 products sold sorted by total? And wouldn't that be super slow on a large dataset?

please i creating inventor management i want to calculate the total amount sold how can i group the total in all fields

Excellent , well explained Can you just suggests a simple use case in mongoDB using aggregation framework and create pipeline or I can show some meaningful data insights so it is useful for business Any simple use case you can suggest

I love you bro XOXOXOXOXOXOXOXOXOXOXO

Hey ! Can't we do the same query with find() instead of aggregate ? Don't get the difference
