Thank you, you were so interested and I could feel your enthusiasm all through. I was surprised I stayed, learned and understood. You're a good teacher.
You are a very good teacher. The level of details is great! Very simple and well explained. Good quality
Thanks for your wonderful tutorial. Keep doing the great work.
Dude, what an amazing tutorial...kudos to you!
these are the kind of videos I subscribe! (without them forcing)
Great video Saggu, keep up the good work brother, great presentation style you have.
The lesson is very clear and gave me a very good basics, thanks a lot!
Great tutorial Saggu! :)
For everyone on linux (without docker-gui) that want to connect to the redis-cli / redis-container
- docker pull redis
- docker run --name redis -p 6379:6379 -d redis
- docker exec -it redis sh
very clear explanation! intersting to see video about caches in js, servlets, or using jpquery
You deserve more than one like for this video, Thanks a lot for sharing sir 👏
Very very great tutorial ,its simple and clear Thanks
Just the tutorial I needed, thank you!

Gaggu. bro you kill it :) . i just want it, other people just want to teach but you try to proved how its work .
Wow, clear explanation and very great tutorial. thanks..
Really appreciate your work and thanks for sharing knowledge 👍 really helpful kt and enhanced my cache concept.
Great and Simple explanation
bahut achchha , great tutorials sardaar ji
Zordar video couldnt have been more better!👌👌👌
Very good video Paaji, I am your subscriber.
For running multiple instances, for folks who don’t have mvn command installed on their Mac (as for me was getting error "zsh: command not found: mvn"), can simply pass -Dserver.port=8082 in VM arguments from run configuration in IntelliJ . Simply create 2 configurations and pass the argument with different ports
Easy and convenient. Thanks 👍
very good video, leaving a comment to support you bro
Thank you very much for your support
Wonderful ..learned a lot thanks
Wonderful explanation.
That very great explanation sir
fantastic sir.
This is awesome. Kudos.
Thanks for the great vdo.
Veer jee Super Impressive😎💯.
you are gem sir
Wow that was amazing!
Thank you Sir
Awesome video
Very nice!
Thankyou for this wonderful tutorial. Can you make additional tutorial which can show how key and other properties can be used to make this more efficient?
awsome thanks alot
Thanks!
Thanks for this great tutorial. In some of the other learning videos, I have seen people using Redis Clients such as Jedis whereas you haven't used it. Is there any particular where one should use Redis or Redis Client?
awesome
Saggu ji please make more videos on java technologies
thanks
Hey the video was really nice. Can you create a video on the docker that you talked about in detail. If there is already a video by you on docker, please share the link
great tutorial, is this a second level cache or a distributed cache? thanks!
Distributed but can be used as a second level cache too
Can we have an example where we use both distributed and in-memory cache ?
can you please explain how does it know how to connect with Redis? Redis can be in different server or with multiple instances.
What is the configuration to connect to redis, is it just adding dependency and using @enableCache and @cacheable
At what situstion do we disable cache in prodution as you mentioned? We need cache in prod mostly?. Thank you for the KT.
Determining when to deactivate the cache is a complex matter as it heavily hinges on your specific usage scenario. One plausible rationale for doing so is a consistent need for real-time data updates from your upstream system. In such instances, opting to disable the cache or implement frequent refreshing may be preferable.
@@SagguUK Thank you.
Great tutorial, but you should show the keys are getting created in redis ( docker instance in your case).. I tried this example but done see any keys in docker
How can we configure a different host and port for redis, incase we run it on a different machine, or a different port ?
Got It
spring:
cache:
redis:
time-to-live: 10S
data:
redis:
host: localhost
port: 6379
i only can use shared cache if i have two instance connecting to the same database right ? but if i have two instances and each instance connecting to a separate database i dont need to do this ? or all depends on my requirments ?
Shared cache has nothing to do with your database as distributed-cache is maintaining it's own state. Your app can connect to same or different database. What you put in the cache will be available to all the connecting nodes.
Hi Saggu, is it same for Spring 3.0.0. I am following the same step but somehow it is not hitting Redis anyway. Application is working though.
how to setup distributed redis server for a multi-cluster environment in kubernetes?
Nice vieo. 1 query.. Why didn’t we require JedisConnection Factory ? (And any config classes for that matter)
Hope you mean RedisConnecion? Spring will use default redis connection settings and will try to connect to localhost. You can always override these things.
I tried in windows. Ran redis-server.exe. And application.properties has host :localhost, port : 6379 but i get an error unable to connect to redis. nested exception is io.lettuce.core.RedisConnectionExcetion. Unable to connect to localhost:6379. Please help
Sir, how the application instances are able to locate REdis server ? you have not configured its location in application.properties?
It's because, he's using Redis in it's default config, i.e. using the default port.
And when Redis dependency has been added in pom.xml, spring boot will auto configure the Redis connection, since Redis is already running in the default port.
At what level do I have to put the annotation? What if I annotate a method in @Controller?
In Spring Cache, you can place the caching annotations at different levels depending on your requirements. The level at which you put the annotation determines the scope of the caching behavior. The common levels where you can place the caching annotation are:
1. Method Level
2. Class Level
3. Interface Level
4. XML Configuration
The choice of where to place the caching annotation depends on your specific use case and the level of granularity you require. Typically, placing the annotation at the method level provides the most fine-grained control over caching behavior.
what if the server go down? how to make it skip the server and go to db
@CachePut is not working for addProduct and update Product Redis, i have imported your code
How does spring application connect to redis cache without even configuring connection in application.yml?
It’s using the default configuration details.
When we add other products and when hit getAll then in redis cache not updated it show past data? Any solution.....
Please not update just add new data but in redis cache not get real time update
Even I faced same issue, he didn't explain about add and update in right way
Getting Serialization error any idea why ?
Can you provide stacktrace?
please add subtitle
You can enable them in TH-cam video
Clear and easy to follow
It's a really cool video
