I would be really glad to see videos of gcp !

[@rockboyjazz]

This is beyond awesome :D, need more videos like these !!

[@shivraj777]

Can you have video explaining topic : spring boot + jpa(with mysql or any external database) + redis cache which will talk about providing crud operations efficiently?

[@nklvijay]

Thank you so much and good explanation about URL shortener

[@ILuvBilli]

Super boss, you know everything, where are you working?

[@TechPrimers]

Does that matter?🙃

[@vivekatbitm]

Thanks for the video, How did the spring service automatically linked to Redis server which you had already installed n running on your system?

[@simplechannel7859]

You are the best

[@sumanchandrasaw7637]

Please make a video of ControllerAdvice and in microservice architecture how exception is handling.

[@sumanth712bs]

Sumanchandra Saw : I would agree to that

[@bhargavasurimenu7850]

Hi - Can you please clarify where we mentioned the Redis hostname and port to store the URL in side the Redis Cache ?

[@shareefhiasat9746]

Unique post in my opinion

How to connect redis cluster by using service url?

[@sahilGupta217]

Can you please tell me how this Redis is different from the normal Db (Postgres, Oracle)?

[@mss8891]

I’ve get data from oracle dB with different schema names for an app. Right now it is configured as list of properties and using for loop we are retrieving the result. What is the best practice to do this? Please advise.

[@LivenLove]

what is the best way to cache images in your opinion??

[@TechPrimers]

Using CDN

[@maheshrebba2437]

With redis pub/sub the data should be saved in oracle db with springboot JPA save. Which actually not working. Please explain how to do it. Thanks in advance

Hey. For an internal company project sometime last month I was using Jedis and Spring Boot to connect to a redis-cluster deployed on Google Cloud. I defined Redis related config in a separate config class such as initializing the factory and the template. All worked fine except for the fact that when Redis times out (say VM is down), we don't receive an error handler for us to manually time the function out after a period of X seconds or do anything else. To reproduce this issue, just kill the redis-server on your local and try the controller again. It should time out after a while. What ways do we have to stop the process apart from running the redis-function in an executor service and killing the thread after an interval?

[@TechPrimers]

You can use hystrix and handle the fall backs based on different scenarios

[@AmanGarg95]

@@TechPrimers Hmm yea. But circuit breakers with their own dependency is sometimes not allowed. Anything in core Java/Spring?

[@RamGopalsubbu10]

Hi, I thought the URL shortener will be a clickable one, like bit.ly. Can you tell me how this can be done?

[@minhajmohideen1344]

good one. thank you

[@rahulgoti3864]

Thanks so much

[@vishalmishra1937]

[@pramodcv]

Awesome

[@anupraj762]

Thank you

[@obrienobahi5214]

Great Video, though too fast at some points.

[@mss8891]

Where in real-time people shortening the URLs? Kindly give some example.

[@TechPrimers]

All Twitter links are shortened. Amazon provides shortened links for affliate n product links. Speakers in conference provide short links for the audience. Btw i use short urls at work all the time since they are easy to remember

[@mss8891]

Tech Primers Thanks a lot. Your videos are extremely helpful!

[@avdheshrajput2470]

Nice explanation...I do have doubt about usability....since we return hash during create and during get full url...so not sure how exactly we will use...in Amazon we get shorturl and we can hit that..

[@TechPrimers]

That's no brainer. You can do httpservletresponse.sendRedirect(url)

[@ajaydhiman2368]

You didn't connect to Redis server ? just storing the data into redis !! strange..
