Collection Group Queries in Firestore

How can I implement this in Android jecpack compose?

I want to cater to multiple restaurant clients, should i crea one firestore database with one top level collection for each client or should I create one firestore database for each client? each restaurant admin/owner should see their unique dashboard when they login to the Android app

So there was a time when Jeff used to not sound like a robot. 😯

The collectionGroup has to be handled with care! It can create an excessive amount of reads in firestore and that leads to a bunch of bucks burned 😀

Make one with react

Very nice and helpful video thankyou so much 🙏🏼 🙏🏼🙏🏼

Hello! If somebody has solved the issue of joins in firestore by any method so please forward us the code or logic or please explain me! Its really urgent and important. Thanks.

Can you please create a firebase v9 migration guide.

in 2021, did they just remove it again from firebase? I can't find it

How do you a collectionGroup query limited to items under one node? For example, limited to comments made within chats of a particular organization.

I really thanksful your video. I didn't know make all collection in same name! It's really good solution thanks

If I want to query common likes on an object in the db, between a user and users they follow, would this be the best way to go?

Every thing was great until he started using angular 😖

buh

You didn't show the output in UI of .collectionGroup call. 😐 But still 🔥🔥...

Seems like a lot of people having the same problem hence so excited for this HAHAH

Awesome!

my brain is bleeding... haha! i guess i need to research more to understand... still, great vids... 😅

I have an ask:
When I do this nested consultation, am I charged for all readings being taken? For example, you asked to consult the comments, but did not initially say where, soon, he will look in the posts collection and in the others, if you know it is in the post collection, I will still be charged for the other collections even if I don't want to include them searching for a collection by group?

Can I get all subcollections of a certain set of documents, such that the documents appear in a list of document IDs that I provide? I.e. put a condition on the ID of the subcollection's parent document

Can anyone please tell
Either solutions for
Shorting data using two child by set query

THANKS JEFF!!!! This tutorial is great!

Please slow down.

Is there a way by which I can put where clause in subcollection and get result of parent collection.

Hey just wanted to know something from you. I heard a lot of people say that you should not deeply have sub-collections in firestore for efficiency. Is it right????

This is a very helpful video - but I am confused as to what snapshotChanges() does - is this angular or angularfire specific? Coming from a react background - I'm trying to do exactly what you show in this video - but cannot figure out how this last step works to retrieve nested replies to each comment. Any help appreciated!

Does it count as 1 read for each Group Query? Or it is depends on how many comments return from that query in this example?

Hi Jeff, does this appear in your master architecture course? And does this mean we no longer have to build up on the root collections list like we did before for easily searching relationship data? Or is there still a limitation here? Thanks

Great video, but if I have a query which gave me an array of comments of a post, Is there any way I can also get user data using the reference uid in the post? somewhat of a SQL join, or is that still impossible in Firestore?

how do it this with vue?

saved hell lot of time

Thanks it helped alot

thank you very much bro, great video

Great! I have been waiting for this!!!!!

Do someone know how to make geolocation queries on subollection it would be very helpfl for me.. I ve tried geofirex but works just on collections... Please...

Awesome video! Thank you. What you think is the biggest advantage of CollectionGroup over a normal Collection query. Isn't simple to mimic the same behavior with a top level Collection?

Talking too fast. Consider that the audience trying to understand this

Using collectionGroup Queries for nested commenting has been great. However, if I allow users to delete a comment the abandoned subcollections remain even as the document is deleted. Have you done any kind of cloud function so that when a document is deleted, it checks lower level collections and removes them recursively?

I wish I could upvote this a million times. I hope that this channel makes you a zillionaire dude you deserve it

Thank u for this awesome video

Does this only work for 1 document who has bunch of nested collections(like u showed end of the video of your backend)? Or can we also query every posts(document)'s collection called "comments" and their nested comments with 1 command?. That would be crazy....Great video

Thanks Jeff. Now how about refactoring this for Flutter with Provider?

What is the name of the background music you use in your videos?

Awesome video as always Jeff!! It would be very cool if you could do a full course on firebase Rules.

Finally, great job Jeff ^_^

This was helpful. What about the Firestore rules that goes with them. Can you do a course on Firestore rules? This needed. Especially advanced rules.

Super cool new feature! But now, you have to review your data modeling course :-p

This is amazing, yet another feature I was anxiously waiting to use.
