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!

[@maghani.official]

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!

[@TenthFir]

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

[@ProSahanj123]

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

[@case_tips]

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!

[@reagandesigns6432]

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!

[@raghavanaliassaravananm1546]

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

[@tinjothomas3766]

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.

[@ameenschools]

very useful my friend. i really needed someone who can facilitate mongo DB aggregation.

[@kaboom3]

I just smash the subscribe button. I love your explanation on aggregation. Aggregation presented itself to me like spaghetti. Therefore much appreciated.

[@nietzschebietzsche]

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.

[@kuzco7061]

[@mangeshxjoshi]

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

[@maxisaez20]

Thanks Mike, it was very helpfulness

[@vaishalisingh0414]

Well explained

[@skateforlife3679]

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

[@hyperborean72]

I guess we do not need {$match: {}} when calculating the money spent by each customer - no filter is used, so $group must be enough

[@ibadshaikh2215]

Great Explanation

[@Middollo]

great vid, answered my question

[@salmam_k4571]

Thank u so much for your help

[@sapinderpal2534]

Excellent explanation! However.... everything in light mode? 🥴

[@CaribouDataScience]

Thanks that was interesting. How do I create a new collection from the results of a aggregation?

[@kumarmanish9046]

Loved the video!

[@Tiagorockman]

This helps alot. Thanks!

[@mshaynerushton]

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

[@jeffjustjeff2891]

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?

[@sitrakaforler8696]

Man i love you thank you !!!

[@abdulfataiabdulrahman5565]

Thanks Mike

[@nik08101986]

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

[@Berkeli]

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

[@surfinbird71]

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

[@danielzuzevich4161]

Thanks man.

[@akashnag3879]

[@tiagogon]

2 hours ago mongodb was just a techbuzz word!

[@classicguy7813]

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

[@ayush7099]

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

[@mulllhausen]

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

[@salehsoleimani]

perfect , thank you very much

[@mrudulaa1061]

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

[@rataozinhoster]

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

[@slimefunoriginal]

sir, please help. i have schema users ex [id,name,email] but, after 1 year maybe, i must change the schema to [id,name,email,phone]. how fix this. i have 1000 data. please helpp

[@aschrider]

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.

[@russelldriver6394]

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

[@gregflln]

thanks !

[@noorulamin2652]
