But redis is still ultimately single-threaded application. How does modules solve this issue? The more complex the load, the slower it becomes. Sure, it can handle dozens of thousands (hundreds even) get/set requests but what will happen with this complex stuff (search/json etc)? Another point - persistence. To use redis as *primary db* persistence is a must (otherwise what is the point of DB if simple reboot will wipe everything out). Enter AOF/RDB, which dramatically increases requirements for RAM and slows things down (because storage is now involved) Wanna scale? Enter replication / cluster with tradeoffs of their own Wanna do it all yourself? That's pretty complex stuff right there and requires ops expertise. Wanna use json/search/bloom/etc modules? Welcome to redis cloud Using DB in the cloud? Yeaaah, very good idea to go from your backend to different DC for primary data or (even better) cache..... Redis is great, but it's far from "one size fits all" solution especially for "primary DB" role

[@cyborgamish]

Nice video, as always. I don't think it answers the question, though. My preconception about Redis is that it will not handle storing large amount of data with complex relations. The amount of data and complexity is relative, but when building a new project, forward-thinking is important. Will it scale well ( cost effectively ) ?

[@guillemgarcia3630]

Probably not. Just look at how expensive redis memory is compared to a traditional db. Also, you deal with non persistence because of in memory db, and others. It's nice to be promoted to show how to write an app like this, but you're lying to now a million people if you don't mention the downsides. Remember fireship is really good at editing videos and explaining programming in general, not necessarily at running things at scale.

[@Denominus]

Redis does offer a way to scale horizontally (memory) with Redis clustering. However, there is no way to run clustered Redis without the risk of data loss.

[@bigmistqke]

​@@specy_ but what's the actual storage limit? Maybe that's enough for certain projects with certain data requirements. As I can see from docs, it can handle up to 4.3B keys per instance (in practice handling 250M keys per instance). And every has can hold up to 4.3B elements.

[@Nitr4Oo]

Why do you think not any big project actually use Redis as a primary database ? This video is just marketing and pure lies. You cannot scale with such system, disk drive memory cost way less than ram and nowadays we are at the ssd nvme technology where the disk drive speed won't really be the bottleneck anyway. + Ram can be corrupted by bit flushing..

Well if data is the volatile part of the memory, I wouldn't wanna store data in RAM. If it's persistent how is it different from sql Or noSql

Redis also persists to the disk so it can be rebuilt to RAM when the db is restarted.

Redis can dumb data to disk at intervals that you choose. Also, after an x amount of changes.

How cost efficient is Redis? There's a lot of info on tech features, but I have yet to find a comprehensive analysis of different database solutions. At the end of the day, choosing a database is a business decision, so I really wish the monetary aspect was more developed

[@joopie46614]

The way nextjs handles connections I think is very bad. Constantly reconnecting to the database is going to cause a lot of overhead and cold starts if your app does not have sufficient traffic or nextjs feels like invalidating the session. This is what turned me off from using nextjs.

I don't mind this channel showing sponsored content, as long as it is presented clearly as such, and as long as it is not spreading misleading information that will waste the time of developers.

This video promotes the idea that Redis is fine to use when you need consistency and safety, it is NOT. It's really important to understand that in all of Redis' high availability modes, some data loss is normal. There are ways to mitigate that to some degree (not completely!), but they sacrifice Redis' performance gains. RedisRaft is working to improve this, but it is not production ready.
