Best structure database for real world project like shopping products or post.
1. Structure for feeds in social media app
2. Advanced querying with multiple fields
3. Possible issues if your app gets 1 Million downloads in a day :P (Best practices to make sure things don't break on scaling up)
4. How to maintain consistency of duplicated data
5. How to deal with aggregation queries when device is offline. For example user clicked like button. Like count needs to be incremented but transactions won't succeed or cloud functions won't execute as device is offline.
6. Complete real world examples for social media, shopping, messaging etc.
#AskFirebase How do we backup and restore databases so we can have PROD and DEV environment? In SQL, we can simply perform backup and then restore it using a different name.
My startup is based in Indonesia, currently building a new Android app using Firestore as the backend.
We need to have PROD and DEV environment. DEV is for Internal Test, Alpha, and Beta.
Topics like data optimization and writing queries.
Your explainer videos are amazing
Your's too.
Yes
so is your channel
Thank you guys 💚
Your's too bro
Todd is definitely one of the best presenters. Would love to see more from him.
True
Instant fan here. This is so understandable and engaging. Much better than any other tutorials I've seen in a long while.
A BIG thumb up 😅 for this video.
@@ToddKerpelmanCorp you remind me an actor Robin Williams. Thank you! 👍
I was looking for a comment about his thumb, thanks !
Came down here to leave the same comment ;-)
I should have watched this video before developing my app with Firestore. Everything makes so much sense now.
After watching this, I immideately feel like I understand what the core idea of firestore is and the difference compared to a SQL database. Totally awesome
This is an awesome introduction. Excellently clear and to the point explanations of the basic concepts with all the important context.
This guy has got great talent as a teacher.
This is one of the best videos you guys posted about Firestore. Really good one! I like this guy explaining.
You actually addressed everything I was thinking as someone coming from a relational DB background. Impressive! Like you were reading my mind. Still not entirely convinced but trying it out.
Was it worth the trial ?
the guy is briliant
himself!
kept me hiper concentrated for the whole video. awesome
Why is this video the absolute perfection?
Really well explained! I kept thinking to myself questions as you went, like "How can I fetch related items without joins?" and "Won't that result in duplicate data that can be out of sync?" and each time within less than a minute you brought up the same question and gave great answers :)
"In the Realtime Database world, when you retrieve some element in the tree, you automatically retrieve everything below it. And that would mean downloading potential hundreds of [elements] anytime I want to grab a couple dozen [elements]... But in Cloud Firestore world, queries are shallow by default." (This is a big point that a lot of beginner Firebase programmers should keep in mind).
But if you actually need a lot of data and everything below it, you need to create a lot of queries because Firestore is shallow by default and that's a big deal. It all depends on the way you're modeling. You can use indexes to help in this process of querying and some techniques in Realtime Database too, as well you can do that in Firestore. NoSQL is a fun world to explore! (:
@@brianoliveira5471 Oh my, I'm getting a heart attack just thinking about it. 😬 Why would anyone want to use it?! Can someone explain, please?
@@klaudiaadamus3353 are you asking why anyone would want to use shallow queries?
As a developer with a long history of using SQL databases, this is the exact information I was looking for!
I remember the time when I am new to no sql database. So confusing. But now, I am enjoying and have understand this no sql database.
Now, I am using cloud firestore db in every app I am working for school. It made my work easier and faster. Thank you, firebase team! Especially to Todd, big thumbs up for you! 👍
Completely lost when I first encountered the reference of “Collection” and “documents”, making the specific relationship was hard, but now I can see all of the benefits in doing it this way, thanks for the video, it is a recommendation sorely lacking from guides.
We appreciate your support, Juan! Thank you so much for leaving this feedback for us 😄
Anyone in 2024...🤚
Yes
Looking for me
Oh man! If all videos in the internet would be explained like this humanity would get the next level his evolution! Thank you so much!
Great explanation!
Possibly the first video I've ever seen where the presenter's "You're probably thinking _____, right?" interjections were in fact precisely what I was thinking.
Thanks for the love! We're so happy you found this helpful!

Happy learning 😎
It's a luxury to have this video series. Thanks for your work .
I have been using Firestore for my app. I would recommend fixing the following deficiencies prior to coming out of BETA:
1) Ability to use the not equal operator "!="
2) Support for OR logic in where clause
3) Offline support for Web.
4) Support for Android in React Native (Android does not currently work with React Native without unsupported workarounds).
As of the current state, I would only recommend Firestore for very simple MVP's and concept testing purposes. I would not recommend it for a production application (hence why it is in BETA ^^)
I understood that with RNFirebase you could use firestore on android, it's not possible?
Dude this is a complete video explaining why there is no such a thing a SQL query and still, you ask for "Ability to join...", seriously?
Offline support for web is there by calling enablePersistence? Am I missing something here? firebase.google.com/docs/firestore/manage-data/enable-offline
Aquilino Méndez you are fine if you use that library. I should have specified that I am using expo, which does not support that library.
cutiko thanks fam
10:56 Firestore rules
Firestore rules:
10:59 first rule: collections can only contains documents nothing else
11:04 second rule: documents can only be 1 MB less inside
11:09 third rule: document can not contain another document
11:15 a document can contain collections of documents, and each documents a collection of documents, and so on
11:23 fourth rule: root can only contains collections
11:47 query
"Worst thing to happen in programming, since GOTO statement" I am going to borrow this line.
Awesome Tutorial !!
That's the best intro description I've heard to describe a NoSQL database. Thanks!!
Glad you like it!
Todd, I love the way you talk, your jokes.
I wish you made every tutorial
You are really a genius, this is one of the best videos I discovered about Cloud Firestore.
awesome explanation!! "Why optimize for the thing that happens 1 time instead of the thing that happens 7000 times" -> That's makes a lot of sense :D
My education is in relational databases but the fact the Google hosts and scales the database for you has me hooked
This guy makes the best videos for real. He should make all the videos for flutter/firebase.
Thanks for the love, Chris! Glad you enjoyed the video 😎
Be sure to check out the links in the description for even more great content!
i was confused in firestore but your video helped in understanding it .enjoyed a lot.
We're glad to hear the tutorial was helpful! Be sure to check out the links in the description for more tips and tutorials 😎
What a talent for presenting information. I could listen to this gentleman all day. Great job. Looking forward to running video #2.
Dude, what a great video. Very easy to follow. Great explanations. Just the right amount of humor. Thank you! :)
Describing complex things in a simple way. Thanks!
"Since Go-To Statement" LOL IM DED😂😂😂😪😪
The drawings and the clear and step by step explanations with examples are making it a great video along with that great sense of humor. Thank you so much :)
this is the best series since bread came sliced
Glad you enjoyed!
This video is so easy to understand and giving examples at the right time when I started to get confused! thumbs up for you
That was the missing link for me. Didactically outstanding Explanation, and Presentation. Thank you, Todd
I'm new to NoSQL and was confused as first, thanks for your detailed and easy to follow explanation!
There's no sequel for that thumbnail.
You described the topic very well, thank you.
Thanks for that!
This guy is crazy good at explaining, Well done.
Hope the thumb is better (and that it did not take 4 years to heal).
GREAT video. Thanks!
Incredible explanation, that's some proper communication skills right here! Thanks a lot!
This is my introduction to NoSQL and the collections make sense now to me
Perfect explanation. Humankind requires more of such.
Looking forward to this amazing series.
I'm just learning about Firestone for the first time. You did a phenomenal job of explaining things here! :D
Best noSQL education short I've ever seen.
Wow! I would like to say that anyone or any company who make some kind of tutorials video should take a good look at this video for how it should be done! Amazing clarity. Thank you.
I've watched dozens of videos about NoSQL and SQL databases but none of them really painted the real picture. This video is literally the best out there! Now I am excited to follow up on the remainder of the series. Thanks so much !
This is a fantastic video. Very well explained and the pace is spot on. Are there any other episodes in this series. If so, how do I find them?
How exciting! Looking forward to this!
Wow I was expecting you to cover briefly on NoSQL before moving on to Firestore
But you also cover the essence of SQL
I find it very insightful and would highly recommend all starting out as backend to view it.
This is the best explanation of why to migrate to Firebase: is a great serverless! No pain for developers, fast queries and scaling is not an issue
Finally a great explanation from Google!👍
whoa did any one notice on PC at 15:11 when author says subscribe to our TH-cam channel the subscribe button have a animation effects outside the video this is super cool!!!
That's solid! You managed to explain to a database newbie what a NoSQL database is. Thanks!
I've been playing around with noSQL db a bit lately but this was actually a very helpful explanation of how to model the data and how it differs to relational.
Good job making a dry topic actually fun to watch!
This is an awesome introduction, no doubt about it. But I expected few examples running on firebase/firestore to understand how it's really done.
best teacher on youtube
Thanks for this videos,, just what i was needing in this moment of my life.
You're so welcome!
i studied sql databases for and year and this is more clear. Thanks.
You got my reaction 😂, i really freaked out and you said every worries i have! thanks for creating this video, I learned a lot
Awesome video Jeff. My first time actually learning about NoSQL after just hearing about it for so long. You've made it look very easy :)
Thank you guys! This was really nice.
Glad you enjoyed it!
Great intro. I'll now watch your other videos. Thanks heaps !
thith guy gets it. thith was dope. appreciate it thankyuhthomuch all yallth
One of the best tutorials I have ever seen!!!
oookay .. thats some top notch explaining right there , keep it
Hi, it's really a very good video ... the contents and the animations you used ... If you allow, I would likw to ask you what tool di you use to make such animations, tables, arows ... Thanks
Does this mean you would have a "Reviews" collection for every "Restaurants" document? So excited about upcoming videos.
Fantastic
Thank you for this video series!!
You are so welcome!
the best explaination about nosql
Great video. I recently had to do some data duplication in order to accommodate certain user needs. This felt really dirty, but it's relieving hearing you talk about this like it's okay to do here and there.
Happened to to my as well this couple days, have you tried to keep reference to your Id's in an opcional value of your model? It works for me when I retrieve the documents so you don need to duplicate data
Brilliant stuff. Got the sample IOS apps working with read and writes to my console and figured out the data model required for the build. Time to build the rest of the structure.
The world needs a new type of database.
This is great video!
I cannot wait for "Future episodes"!!
wow!!! just wow!! excellent pace and extremely well presented!!
Fantastic presenter! Great video thanks
Glad you enjoyed it!
This is the best guy described it so well and fun, thanks a million :)
Alert alert dont watch this video this guy will convert you, he's that good🤓, keep it up bro this is great.
I hope this guy is getting paid a lot cause his videos are fire
Thanks for the good instruction video its easier to understand than documentation reading alone.
Todd is a fantastic presenter / speaker
Awesome explanation. Would give a big thumbs up...but I see, you already have one.
hahahaha 7:03 that's what I'm currently feeling 🤣 having only SQL background this nosql thing is driving me crazy.
Please keep bringing more videos on firestore. A separate playlist would be best :)
Nice! I'm devoloping my firsts apps with Firestore.... and boy! I love it, so simple. Great job guys! and keep the videos coming
Haha I love the creativity in these videos.
super easy to understand. thanks a lot!!
Thanks so much. I'm switching over from SQL to Firestore. Wish I would've learned this first 😭
Informative video. VERY NICE!
Glad you liked it!
Love the speaker - he is awesome!
Both Cloud Firestore and Mr Todd are belovable
#askfirebase Thank you for this great series, I have a model like the following:
Collection: Place
String name
String description
Int numberOfVisits
and so on
Q1: for the first two parameters ‘ *name and description* ’ I need to make it *multilingual* what is the best structure to make it so while keeping minimal data downloaded and the minimal number of queries?
Q2: you're talking about having a sub-collection for reviews, but what about having a third collection for the relation between users-resturants-reviews ?
Best,
Yusuf
wow, now THAT's a high quality explanatory video!
Excellent illustration on what noSQL is. Thanks so much :)
Just fantastic.
What an awesome explanation, thanks!
