As always your every video is unique and very informative. Every time you come with some use case approach which is very impressive.

@TechPrimers Год назад

Glad you acknowledge that Anand. That's the vision of the channel right from the start. Glad i could still continue it. I put extra effort in choosing a topic

@kanishkumar6176 Год назад

Very informative content.

@ashishsengar87 Год назад

nice demo. Very well explained in a short time. Can we do TLS termination at spring cloud gateway like nginx. If so can you please make a video on that.

@hounangogogo 8 месяцев назад

Hey thank you for this amazing course, at 4:25 how did you configure YAML template? This can save a lot of time to write line by line

@sethunest9907 Год назад

bro pls tell what algorithm that you using like token bucket or any other

@jpchennai Год назад

Just to add, when say a lot of options are available. 5:05 Could you please point the reference material or show a screen shot from we can lookup to. By the way this is my first spring cloud material view and its awesome

@JaNaMSoNi Год назад

Hey bro can you please make a video on centralised session management using redis spring boot. Also please mention how to handle if Redis server down

@TechPrimers Год назад

Sure will try

Hi Ajay, one question , why have you added redis here , rate limit configurations can work without redis as well for instance and we can scale too ?

@TechPrimers Год назад

Hi dev, redis is for storing temporary expiring data. And redis provides TTL on data out of the box. Hence redis is beneficial here for storing the rating limiting data for every request, also being a cache it’s faster than DB upsert

@vinodhreddy6227 Год назад

Excellent, but create all fault tolerance concepts in spring cloud gateway, so no need to go resilience 4j concepts ryt???

@TechPrimers Год назад

Not everything can be added into the cloud gateway. Fault tolerance comes when our app connects to other apps. API gateway handles only incoming requests. We can add circuit breaker in gateways but we cannot add exponential back off in the gateway as it's controlled in the app. So we will still have some bits in app

Hi Ajay , I m a beginner, can u tell is it necessary to learn curl ? Why you have used curl and when to use it ? Thanks!

@TechPrimers Год назад

Hi Vikash, Curl is a cli utility for calling http urls. Most of the time we just google and get the syntax. 😆

@vikashgaurav4126 Год назад

@@TechPrimers yes I checked that it is used to transfer or recieve data from a server. Then u could have used postman , right?😅

@vikashgaurav4126 Год назад

Does Postman can handle any type of protocols or just http ?

@kunalsharma-zc2ho Год назад

Hi Ajay, Had one question In case if wanted to pass header's and body will it be possible with this rate-limiter gate-way to Original request.

@TechPrimers Год назад

Hey kunal, i dint quite get your qn. Do you want to send during 429 or from the gateway to the app

@kunalsharma-zc2ho Год назад

from gateway to app exact same request ( Consisting Body and Header ) for such cases do we need to handle to gateway level.

@phyohtetpaing44 Год назад

How can we scale redis in this kind of rate limiting.Redis use only one thread.Spring can be loadbalancing but how do we scale the redis in both horizontal and vertical way. By defaults it can’t handle the load especially if we are working with microservces or http load balancing to single route.

@TechPrimers Год назад

One option is to have cluster mode enabled on Redis for scaling redis. The other option is to have the fleet size of your Rate Limiter scale with your service. Meaning, if 1 node fleet supports 10RPS. When you increase the fleet to 2 nodes, by default you get 20RPS with 10RPS config. You can have it scaled across regions and geographies to scale it to planet scale
