Save bandwidth while querying in mongoDB

[@RiteshMagreIT]

Sir I am enjoying your videos on mongodb. Long videos are also ok . You explain very nicely.

[@siddharthbehra5250]

Hitesh Sir, since last 2 years , I was hearing about nodejs, mongodb and react, when I was in 3rd year of my college, I always use to think it must be so tough because it is today's hot skill, it will take a lot of time to understand that, and I never actually started, somehow got a job, when the requirement came for node with no sql, I referred your your mongodb tutorial, and in just one day, I know all the basics of mongodb to start working on project, thank you so much for making our life easy, really appreciate your work. Again Thank you so much, would love to meet you in person some day

[@saswatibanerjee6199]

[@ShakeelKhan-pz6zl]

The newer versions of mongodb do not require you to use the function "toArray()". As it already returns the objects in the form array.

[@ShakeelKhan-pz6zl]

The command "mongo" to fire up the mongodb does not work with mongodb version 6.0. You need to use run "mongosh" instead.

[@madhavgarg322]

please make long videos. I totally enjoy this series of MongoDB.

[@alokkotwalla330]

And yaa you can make long videos no problem about that

[@alokkotwalla330]

fetching email :) db.studendData.find().forEach( (students) => { printjson( students.email ) } )

[@hardikvegad3508]

db.studentData.find().forEach((student) => {printjson(student.email)}) this worked for me....

[@kameshsobrajani9539]

solution will be let c =[]; db.studentData.find({},{email:1,_id:0}).forEach((email)=>{c.push(email.email)}) all the email values are in the array c

[@diotixz1334]

[@sumer420]

iam new to mongodb .and i want to know how what is best practices and what is not best but optimum for my needs 1) get all the data and sort and filter client side (i know this is bad) 2) filter data on mongo atlas and then sort client side (dose it make any difference to save resource on server ) 3) filter and sort on server and just show data on client what should i do and what are best practices. like i get a list of documents from server with embedded objects. 1) should i use project and remove embedded objects i dont need.( does this use more server resource) 2) or i get all the embedded objects and hide them with client side logic

[@sahajkedia1589]

[@farooquitaha]

I have millions of records in mongodb and I am using indexes to boost the search process but when I use find with count to count the total records before limit it extremely slows down the process.Can you let me know what I am missing here.

[@adityasoni1639]

I think...am too late to learn it..!! I think this should be the first comment of 2021...!! 😅

[@alexnedin]

Thank you very much Hitesh, you’re helping a lot. Mongo is awesome, I’m having fun studying it. I purchased your NodeJS and ReactJS courses, and am very happy with your way of teaching. I’m also definitely going to buy React Native after ReactJS and, most likely, some other courses. Keep up, you’re an amazing teacher 👍

[@pavanagarwal6753]

Hey hitesh I had one question not related to this video but related to my project. I had one UI page where I am updating some field with comments and when I am saving that the other field which is date one gets disappeared which does not look good but that date field reappears when I refresh the page.So what could be the solution for it to resolve it so that date field remains unchanged as other field changes.please help man.it would be great of you

[@rohitvijayvargiya2503]

The explanation is really great. Like the enthusiasm!

[@tanayraj2991]

Thank you

[@suraskumarnayak8350]

Doubt: When you said that .find().forEach() is costly since first it retrieves all the data from data base and then does the looping part. So it means that when I run this query from my apllication server, then it goes to the mongodb server gets all the data because I have not given any filters in .find() send this to my application server and then runs the .forEach() there. Please tell me if I understood this correctly.

[@subhamray1203]

Yes my friend, you got it right. This way there is less load on the database server and retrieving data becomes super easy!

[@skillfulactor09]
