Appreciate for your hard work and Thank you very much for this video.

Nice video. But I was looking for one to many Get query also. You have showcased getting users by address (one-to-one), but not getting users by product. Some cases that is important too. Your title says so. Also, having this structure where products go in user object, when say 100 users have bought 50 products and many more people will buy some of those 50 products. Won't it be a bulky database with repetitions?

Why all the people uses Embedded Documents? Not is more inefficient this strategy than use Referenced Documents?

[MohdDanishMansoori-ok]

thank you so much bro for getting this vidioo

You didn't perform update and delete operation on embedded document. Like, if i want to add one more product to particular user, how will we do that?

Any video on pagination in Spring. eg. when doing product search based on sorting on few fields lets say price of product

[vanshkhosla]

Hi, can you please explain how we can use PUT Method to add 1 more array of object of Products in already created User.

[sarojsahoo]

does Id annotation is required here as we are not having relationship concept here & How does Mongo knows it has to create Address Document from User Document . Is it derived from User

[mathiasmartinez]

The example of the CRUD of spring boot and mongodb I think is great, but I suffered to understand your pronunciation in english, for next time try to improve in order to enjoy your great tutorials. Just a good advice
