Caching database queries with Redis can be an incredible way to speed up your API responses. That will not only cost you less database quota but drastically improve user experience as well. Let's see you how can implement super fast caching for yourself!
My GitHub: github.com/joschan21
Upstash (not sponsored): upstash.com/
I wish you a lot of fun implementing caching and seeing the results for yourself. Let me know if you build something cool with it! Cheers

This is very interesting and useful. It will be great if you consider a more in depth video about Redis. For example how to update the cashed data if it is updated in the DB? How to delete cashed data if it is deleted in the DB, best practices, etc. Great video!

Redis is really known as a caching layer but it's also an extremely capable primary database. If you can fit your data into RAM and work with the data structures Redis gives you, you will be a happy camper.

Very good video, I congratulate you. I ask you a question, suppose I have an application with a mysql database, my app calls an api to query and show products to the user, if I implement you Redis to cache the busquedaby that the api first see if you have stored in cache and if not just then go to query the database, with the first user who enters the app Eedis stored in the server cache and then if another user comes and asks to see the products would be set in that cache even if they are different users? The cache has a time and then it is deleted and the search to the database is done again, right? Thank you very much

@karthiksharmaslife2323 6 ай бұрын

Hi Josh, can we do data manipulations directly in reddis cache and push the changes to the Database table without loading data from reddis cache to data table and manipulating the data? In my case data table cannot hold tons of data.

@GamingClubGermany 10 ай бұрын

Its cool but it could be a lot slower than just using the database directly if you using redis on cloud. If you backend need to connect via tcp to a different server anywhere you have a fast lookup but a slower response than using the local database directly. It would only make sense if you have very large requeste. But in general in memory caching is a really good idea but you loose manually editing the database manually (which is not recommended anyway) But good video as always!

but how does that work in terms of latency? one of the advantages of redis is 0ms(almost) access, but when used with upstash there surely is some ping latency. Can you tell if im right? Also what are other ways to implement redis with next, because cant find any :/ ps. gained sub

Correct me if I’m wrong: doesnt Nextjs automatically implement this with their extended fetch API? If a fetch has the same parameters as before it would return the cached value. What’s the difference btwn that and Redis caching?

@joshtriedcoding Жыл бұрын

Pretty sure the nextjs values are only cached for YOU due to the serverless architecture, meaning if you and I request the same resource, my result wont be cached for you or the other way around. With redis, if we both request the same resource, it wil be cached for the later request

Redis has no idea whether the data in DB has been updated. Normally, we use Redis to cache data as follows: 1- Client checks if the data, e.g. key-value pair, exists in Redis. 2- If the key exists, client gets the corresponding value from Redis. 3- Otherwise, it gets data from DB, and sets it to Redis. Also client sets an expiration, say 5 minutes, for the key-value pair in Redis. 4- Then any subsequent requests for the same key will be served by Redis. Although the data in Redis might be out-of-date. 5- However, after 5 minutes, this key will be removed from Redis automatically. 6- Go to step 1. So in order to keep your data in Redis update-to-date, you can set a short expiration time. However, your DB has to serve lots of requests. If you want to largely decrease requests to DB, you can set a large expiration time. So that, most of time, Redis can serve the requests with possible staled data. You should consider carefully about the trade-off between performance and staled data.
