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!

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 !!

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

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

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

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!

every single minute of your videos is golden. thanks

Good start for me. Your presentation skill is awesome.

Thanks Mike. Its really helpful to understand about aggregation.

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.

Super helpful playlist!! Thank you!

Hello mike, your tutorials are really great! one thing I wanted to ask you is, pls make one video on how joins work in mongo! thanks.

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?

awsum tutorial.. thank you buddy...

Thank you so much! please, be my friend! hahaaha I can show you many things here in Rio de Janeiro ... I love your explanation :)

It would have been great if you continued session for advanced aggregation

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

Wow, perfect explanation. Thanks bro.

Thank u so much for your help

Thanks a lot for the awesome video it's really helpful

Thank you very much.

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

Great Explanation

You teach like a rabbi!!.....thanks mike

thanks...... simplest explanation...........i'm subscribing bro

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

very good explanation. I was having problem understanding it. Subscribed...

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

You are amazing my friend

great job Milke, Would you please create a lesson for relations in mongo, thanks in advance

Great explained

Great information

Thanks Mike

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?

excellent sir ji!

красавчек! Супер!

Great teaching

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

how do we sort in ascending order?

nice and well explanation :)

Awesome 👍😁

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.

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

Good to create a Dashboard, thank you.

Thanks man.

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

thanks mike

Well explained

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

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

thanks !

Thank you bro

but how do you still select wanted fields?

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

cool video :)

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

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

Can we convert stored procedures to mongodb?

Hi Mayko, have id on another structure of model. Because names (here referred as ids) can change. How can I reach that data? Thanks really great content

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

Do aggregate functions perform well with large data sets (like millions of records)? We built a report processor that is timing out on huge data sets bc all the data has to be sent to the report processor and then we use math.js for calculations. I’m wondering if it would perform well to aggregate sums and averages in mongo and only transfer the results.

Braaaaaaaaaaaavooooooooooooooo
