[@ragsbigfella]

Thanks for a wonder mini series!! appreciate it.

[@AKSHATGANDHI-di7pq]

I have completed both the series MongoDB basic to Advanced and Aggregation. I don't think I have learned anything this much faster and with understanding of scenarios. Thank You Sir 👍🏻🙇🏻‍♂.

[@HiteshCodeLab]

Great job!

[@chandnijha]

Hey Sir, I have completed entire MERN with advanced MongoDB aggregation tutorial from your channels Chai aur code and this one. You have made the world of web development lot more simpler. When I would recall best teachers of my life, your name would surely be at top. In a world where people donot help or even help for some selfish reasons, you are working selflessly for us. I feel your spirit needs to be cherished more than your videos in youths globally. Tons of love and 🖖🙇🙇🙇🙇🙇🙇

[@mahendrachennupati2289]

I just wanted to say a big thank you for your amazing explanation of aggregations through real-life scenarios! The way you simplify complex concepts makes it so much easier to understand and apply in real-world projects. Your teaching style is truly inspiring, and your content has been incredibly helpful. Keep up the fantastic work-you're making a real difference for so many of us! similarly small request from my end that is please let us know where we can practice these king of challenging scenarios with mongodb. rather than in my practice projects.

[@lakshyathedestiny7674]

thankyou so much bhayya 😆😆😆😍😍🤩

[@shankarraj3606]

I think we can use Unwind also, it also provides the same result " [ { $lookup: { from: "authors", localField: "author_id", foreignField: "_id", as: "author_details" } }, { $unwind: "$author_details" } ]" response:"{ "_id": 1, "title": "The Great Gatsby", "author_id": 100, "genre": "Classic", "author_details": { "_id": 100, "name": "F. Scott Fitzgerald", "birth_year": 1896 } }",

[@manasranjan4]

Really its very informative. Please make video in same series for combining results from multiple collection through unionWith

[@genztechman]

Amazing series

[@aloksharma7871]

Hey hitesh this was an wonderful series accumulated lot 😅 and why not go deep dive into joins more. keep alive this type of small series ✌️

[@aakibali2397]

sir after seeing your chai and backend i was little bit confuse about aggregation after seeing this i got very clearance about my doubts and now i have confidence that i can do that assignment very effectively #chaiaurcode

[@victorchidi9973]

Hi Hitesh. First of all, thank you very much for this series, yeah. Based on the aggregate function, how do I filter books by birthyear of the author? Also, how do I search books by author name?

[@golubhattuk01]

completed this playlist thanks for this playlist sir ji

[@ashishsng]

[@FaizanAli-m1w5r]

[@BujjiTheCoder]

Chai or code channel backed ho gaya hai

[@rakib_bhai74]

❤ From Hindi Channel sir :- 🎉 author_details : Array ho vi sakta he """""---"""" Author can be multiple, Can we implement it with the help of nasted lookups (sub-lookup) ? ❣️❣️

[@rakib_bhai74]

LMK sir 😁 ❤❤❤

[@freekeys]

Can we have a video of fast/advanced queries with relationship 💯💯

[@saqibullah7286]

Sir Please can you bring more videos on MongoDb aggregation

[@msaleem9704]

There is Four types of join (Left ,Right Inner,Outer) $lookup operator acts as left join in that

[@abhishekseth7187]

Thanks sir

[@JSDEVD]

hi hitesh sir can guide more viedos about joins

[@davidnickson5043]

Hey Hitesh, I want to make an Atlas Chart, and combine data sources. Is this possible?

[@sergioramirez7125]

What if the result author_details needs to be at the same level of the test of three attributes instead of nested into another object, while also keeping the values from the rest of the attributes?

[@HammadAliKhanKhan]

Love you hugya sir g

[@reromsp]

Helpful Thanks

[@ashwinpatidar2878]

helpful Thanks.

[@shehza-d]

Where can i get the list of questions??

[@DE4DP00L-cs1ts]

which fields require '$' before name and which dont?

[@ashishsharma6838]

Where fields value are dynamic not static

[@khaleelrehman5327]

Hi, I can't access the course, please check and verify. I want to be able to start using the course as soon as possible. Please let me know if there are any issues and I will address them as soon as possible. Thank you for your help. I have sent a mail to mail but it shows that this mail is not currently available.

[@miguelcosta4450]

Hmm, the $lookup never update this new related information to the actual collection right? This is just for querys basically... I tried with other example in my shell and the new data will be aggregated in "as:"grades_data". But they never update the actual collection with grades_data right??

[@siddesh1210]

First of all thankyou for providing such Gem content❤ @hitesh. Also want to bring you notice that while sharing my this learning of MongoDB aggregation pipeline on Linkedin I can't able to mention you in caption as your profile is not visible while tagging @hiteshchoudhary. So for now have used hashtag but been part of @chaiaurcode family its been concern why can't able to tag our person who's providing such amazing content on YT. And again thanks for creating such brilliant mini playlist and getting us understand of MongoDB pipeline❤

[@mantragor8150]

This was not so in depth sir... Lookup is a complex and powerful stage in aggregation pipeline it should not be such sort. Disappointed from this....

[@aaa-os3pj]

Could you suggest any sources for learning it

[@rishabhpal3907]
