Context Api and Now this one. Both are awesome videos. i am stuck in Replica around 2 days. Now after this i complete Replica and now transactions are working perfectly. Thanks Mittal Sir
@Truly Mittal, well explained sir. The topics and the explanation were fully structured and systematic way. Thanks for sharing your enormous amount of knowledge with us and look forward to see more and more from you.
I have i small question as primary went down and few hours later it up again question is after it up all the data transactions happened between downtime will be copy in to the database that db went down?
You are really awesome man ☺️. I have a question man. Will the application we design that uses the DB know that it is having a failover setup or it will have zero knowledge on that. What I mean is which url should I specify to connect to the mongodb cluster so that it doesn't matter whichever instance goes down. It may be a noob question but please help with that if possible. Thank you.
Hey yourstruly!! Saw ur android playlist, it was just awesome!! Do add a tutorial on how to access file or file list from internal/external storage to the app..
I have a situation where Primary and Secondary1 wen down so all I have is Secondary0, I deployed three new servers Primary,Secondary0 and Secondary1 how would I replicate data from old Secondary0 that is still available but didn't become primary ?
... I assume to have a shared setup with a cluster you will first be creating a 2 way or 3 way or x way shared setup and then as a 2nd step take each of the masters and add replicas for the ? do you have an example of such.
Hey I have some doubts regarding concurrency in mongoDB. I saw there is a pool size settting while instantiating the client, is that is the way to do concurrent requests? Also mongoDB handles all the read / write operations between all these concurrent services automatically?
This video is pure Gold!... I am so happy that I found this video, bro you are amazing thank you very much! 💙 and no I will never scream Chuck Norris' name during sex, This will never happen 😂

@@mafiacodes it's sharded cluster. if possible I want to combine, both sharded and replica as you told in this video,for large scale,
Better would be to use mongo atlas, since what u pay for individual machines would be more than atlas
@@mafiacodes sorry to distrub what you told is right, but i have a different concept to test . It will enough for me to know sharded cluster.
