What is a NoSQL Database? How is Cloud Firestore structured? | Get to know Cloud Firestore #1

[@Firebase]

Let us know what you'd like to see covered in this series in the comments!

[@uziao]

Please help us with SQL Databases to migrate to NoSQL! :) Greeting from Brasil (Ormando - Colatina/ES)

[@TheGrafox]

Best structure database for real world project like shopping products or post.

[@SreekanthKrishnan]

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.

[@AshishYadav-eh8bl]

Topics like data optimization and writing queries.

[@vigneshr5329]

Todd is definitely one of the best presenters. Would love to see more from him.

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

"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).

[@brianoliveira5471]

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! (:

[@klaudiaadamus3353]

@@brianoliveira5471 Oh my, I'm getting a heart attack just thinking about it. 😬 Why would anyone want to use it?! Can someone explain, please?

[@huntergroton]

@@klaudiaadamus3353 are you asking why anyone would want to use shallow queries?

[@bushbuddyplatypus]

Instant fan here. This is so understandable and engaging. Much better than any other tutorials I've seen in a long while.

[@luisfittkau9322]

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

[@chanlito4896]

A BIG thumb up 😅 for this video.

[@andriys5772]

​@@ToddKerpelmanCorp you remind me an actor Robin Williams. Thank you! 👍

[@enriqueeee]

I was looking for a comment about his thumb, thanks !

[@vitikahappy]

Came down here to leave the same comment ;-)

[@27sosite73]

the guy is briliant himself! kept me hiper concentrated for the whole video. awesome

[@ne2r]

I should have watched this video before developing my app with Firestore. Everything makes so much sense now.

[@waleedalrashed1411]

Why is this video the absolute perfection?

[@epajarjestys9981]

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.

[@jesselima_dev]

This is one of the best videos you guys posted about Firestore. Really good one! I like this guy explaining.

[@CoryMcaboy]

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 ^^)

[@topolichio]

I understood that with RNFirebase you could use firestore on android, it's not possible?

[@cutiko]

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?

[@ValAllenSamonte]

Offline support for web is there by calling enablePersistence? Am I missing something here? firebase.google.com/docs/firestore/manage-data/enable-offline

[@CoryMcaboy]

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.

[@CoryMcaboy]

cutiko thanks fam

[@jamesgaroutte7579]

As a developer with a long history of using SQL databases, this is the exact information I was looking for!

[@gothakane]

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.

[@RadhwenKhelia]

Was it worth the trial ?

[@adityajain5135]

"Worst thing to happen in programming, since GOTO statement" I am going to borrow this line. Awesome Tutorial !!

[@rawtale97]

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.

[@Firebase]

We appreciate your support, Juan! Thank you so much for leaving this feedback for us 😄

[@Glenn.Cooper]

That's the best intro description I've heard to describe a NoSQL database. Thanks!!

[@Firebase]

Glad you like it!

[@pablokatt]

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!

[@AlmostM]

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 :)

[@michelkant]

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

[@Juan-lb5wu]

It's a luxury to have this video series. Thanks for your work .

[@PDXdjn]

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.

[@Firebase]

[@jdcoding1012]

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! 👍

[@eliseerickson5994]

My education is in relational databases but the fact the Google hosts and scales the database for you has me hooked

[@suraj0223]

You are really a genius, this is one of the best videos I discovered about Cloud Firestore.

Todd, I love the way you talk, your jokes. I wish you made every tutorial

[@CodeLove-v6r]

Perfect explanation. Humankind requires more of such.

[@vvmanyam1]

wow!!! just wow!! excellent pace and extremely well presented!!

[@RobertBrunhage]

Will you implement or in queries and also be able to query multiple fields? It's almost impossible to make so that a user is following people and displays all their posts in a feed.

[@netokapps]

This is great video! I cannot wait for "Future episodes"!!

[@CameronChardukian]

I'm just learning about Firestone for the first time. You did a phenomenal job of explaining things here! :D

[@Falzer]

You got my reaction 😂, i really freaked out and you said every worries i have! thanks for creating this video, I learned a lot

[@ellasaro]

Does this mean you would have a "Reviews" collection for every "Restaurants" document? So excited about upcoming videos.

[@ellasaro]

Fantastic

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

[@NandaAcademies]

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.

[@marians.9010]

wow, now THAT's a high quality explanatory video!

[@solmillin]

Great intro. I'll now watch your other videos. Thanks heaps !

You're so welcome!

[@thedevguild7525]

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.

[@madhavmanocha4999]

Awesome explanation. Would give a big thumbs up...but I see, you already have one.

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.

[@LinhLinhBD]

the best explaination about nosql

[@hugolandreville853]

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.

[@lekahuna]

Defensive programming and checking received data on client side are mentioned at 4:20 Should I really check each field of the document for existence and type when received? And if it not matching the expectation use fallback values and log an error (i.e. with Crachlytics)? How defensive are you guys programming your client side?

[@Ninja-nt6yt]

Amazing explanation with precise visuals.

[@phong764119]

7:39 now the problem is when i have to update every (sub)user document, i have tried using collectionGroup so i can get all path of documents and add them to batch and update them. BUT this way have a limitation, the batch of writes can write to a maximum of 500 documents. So is there any other better way to do this?

[@siddharthmanumusic]

Great presentation with illustrations! Loved how you introduced concepts along the way and kept one example going..

[@nimas7840]

Haha I love the creativity in these videos.

[@whatawastere]

I'm looking forward to the next episode. I hope it comes soon.

[@guyincognito5663]

Brilliant series.

Good explanation. I wish I saw this video a few months ago :)

[@kuraibankusu]

It came out today

Me to :C, now I need to change all my code :V

[@rammalvarez2664]

Nice! I'm devoloping my firsts apps with Firestore.... and boy! I love it, so simple. Great job guys! and keep the videos coming

[@yurowitz]

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 !
