Laravel solved race conditions

[@ahmad-murery]

I wish you can make more Laravel courses just like the MySql for developers series where you start with the basics but with good details. Thanks Aaron!

[@bballantyne3]

Your presentation style is ideal for me. Thank you!!!

[@alchemist_dk]

This channel is pure gold, thanks for all the info.

[@SurprisingLee]

Having written almost exactly this locking system to prevent a race condition on Laravel v9, for ecommerce checkout no less, I can appreciate the good design behind this.

[@irvanicsmoke1132]

this is why i subbed for!! Your explanation is always easy to understand and the delivery is so enjoyable :D Would be great if you also explain concurrency control like optimistic vs. pessimistic locking. Thanks once again Aaron!

[@aarondfrancis]

You mean database locking? I might cover that on the PlanetScale channel!

[@JeremyAndersonBoise]

I have been using Laravel for a ten years or so, but not in-depth for the last two. I need to look at this, this looks like a great improvement, thanks for the tip-off!

[@aarondfrancis]

Glad you liked it!

[@FarazSamapoor]

I'm just so happy that we have you on our side. You are a great teacher and visualizing the examples vastly improves the learning experience. Thank you, Aaron! As a side note, I think it would be great if you could clean up the IDE a bit, as it distracts the viewer from the main content. I think hiding the "Tool Window Bars" would be a great start. You can find the option to hide them under Settings => Appearance & Behavior => Appearance => Tool Windows. Or just hit the shift key twice and search for the "tool window bars".

[@aarondfrancis]

Good idea! Thank you

[@spicynoodle7419]

I've requested this topic a few times. Thanks for delivering ❤

[@agussumawigena4565]

sifu, you are very talented at transferring knowledge

[@kirayamato6128]

love you Aaron! The way you explained really makes me easy to understand the laravel and mysql. kudos!

[@davidharting3119]

Maybe it’s a common Laravel idiom but doing while(1) instead of while(true) has a very devil-may-care attitude to it. I must say it shivered my timbers.

[@davidharting3119]

Clutching my pearls!

[@Novica89]

Awesome video and explanation on how to use atomic locking :) Even though I've used them and know how they work, it was a nice overview and confirmation that I was using them properly :D

[@demian.succs0]

I've seen your videos on the planet scale channel and didn't know you have yours own lol, thanks KZbin algorithm to take me to the right place

[@GringoDotDev]

I don't have anything to say except that you make fantastic videos!

[@aarondfrancis]

Well I'm glad you said that! That makes my day. Thank you

[@Voltra_]

You'd be surprised how many web developers don't know/understand that the web is a fundamentally distributed system and thus don't use any kind of synchronization primitives when they're required

[@pookiepats]

Reads like a poser

[@Voltra_]

@@pookiepats try me biche 🦌

[@asjidali5453]

Incredible!

[@thegrumpydeveloper]

Nice that this is built in

[@etiennez0r846]

wow what a clever way to solve locks by inserting a unique key lol never thought of that xD

[@aarondfrancis]

Sneaky right

[@alikaram98]

So good

[@asuramus]

Whats the different between pessimistic locking and cache lock?

[@ajzack983]

does this relate to ShouldBeUnique interface of the laravel jobs ?

[@MrNichuya]

Great video!

[@zinatziaee5000]

Thanks very good

[@gfni]

Great video as per! Can this be used in a simple user request so only one user can do something at once.. lets say on checkout? or is this used primarily in worker/job based solutions?

[@aarondfrancis]

It totally could, I suppose! You might need a little more scalable, robust strategy for that though. If you've got thousands of users fighting over a single lock, that's probably gonna create a pretty gnarly bottleneck. Something like this would be more useful for coordinating backed processes fighting for limited resources.

[@norc]

Does someone know if the octane cache driver is supported?

[@aarondfrancis]

I'm not sure!

[@pablorgto]

Please, make an video about the Drupal 10?? Thank you!!!

[@aarondfrancis]

You don't have to comment the same thing on every video 🫠

[@sezohessen7485]

WOWWWWW

[@Stoney_Eagle]

Did you just use tailwind in the terminal?!!!! Omg 😮😍🤩

[@aarondfrancis]

Haha yup! 07:10 I mention Termwind!

[@Stoney_Eagle]

@@aarondfrancis Yeah I could not believe my eyes, I had to verify this magic 😂

[@aliffiansyahmaulana]

I think its similar to withoutOverlapping() in task scheduler

[@TurkerTUNALI]

Php guys finally enters the enterprise area. Great feature by the way.

[@aarondfrancis]

Haha, I guess?

[@vsakthivel85]

But this lock won’t works if we use file cache

[@aarondfrancis]

Across multiple processes on the same server it will!

[@vsakthivel85]

Thanks

[@lighty262]

Kinda similar to flock function in PHP

[@aarondfrancis]

Does that communicate across processes? I'm not familiar with it

[@lighty262]

@@aarondfrancis It uses file system lock/release instead of caching driver in your video, all php process will use flock function to check wether the file is lock or not, that's how they communicate.

[@thegrumpydeveloper]

Would be cool to make an equivalent in js with other db locks.

[@aarondfrancis]

Yup that'd be really neat! Could be a Prisma or Drizzle plugin maybe

[@SaiyanJin85]

we better stick with redis since it's really easy to share between completely different servers.

[@aarondfrancis]

Agreed! Redis or db.

[@brunocmesquita]

Hey man, great content. Would you be interested in making a video on your IDE and terminal configuration?

[@aarondfrancis]

Potentially! Although I don't really customize my setup hardly at all. It's just pretty standard PHP storm

[@thebirdhasbeencharged]

@@aarondfrancis Font and theme

[@iWhacko]

how are database and file locks surprising? A database lock can be great when migrating data, so it's locked to prevent new data to be inserted. And file locks can be great if a file is still being written to, before reading it. or some other reason.

[@aarondfrancis]

A database lock is not surprising! Using a plain ol' unique key as a shared application lock is surprising, and quite clever. You might enjoy some of my database videos at youtube.com/@planetscale.

[@iWhacko]

@@aarondfrancis Maybe I'm misunderstanding the issue then. I come from a software engineering background. and worked with low-level hardware too. And using a Mutex (or semaphores) to lock stuff is not new, and can also be done with plain-text keys in most systems. so I must be too set into my mindset to miss a point here I think.

[@aarondfrancis]

Some of the things you learned a long time ago, other people have not yet learned! And thus the wheel of time continually turns.

[@labkitadev]

give a real example using job with atomic locks on race condition case like inserting data

[@travelcouple-z1m]

This is like golang 😮

[@vsakthivel85]

But this lock won’t works if we use file cache

[@aarondfrancis]

For multiple processes on the same server it will. Mentioned at the end
