General Question for better understanding

  1. What kind of rate limiting algorithm is being leveraged here? (Ex. Token Bucket, Sliding Window etc)
  2. If we go with Redis as our data storage, does it come with the feature of distributed locking?
  3. If not, how do we enable the same since persisting the rate limit headers are not within our reach?
  4. Is client side rate limiting also possible?
  5. If let's say a particular IP/host has to be blacklisted, is there a way we could just enable it on the fly and avoid manual reboot by reconfiguring rate limit properties of Zuul api gateway service?

Best Regards,
Akshay

Hi @akshaydk-buku sorry for the long time to get back to you, I'll try to answer your questions here:

  1. What kind of rate-limiting algorithm is being leveraged here? (Ex. Token Bucket, Sliding Window etc)

It uses Token Bucket.

  1. If we go with Redis as our data storage, does it come with the feature of distributed locking?

It depends entirely on how you configure your Redis cluster.

  1. Is client-side rate limiting also possible?

This library only does server-side rate limiting.

  1. If let's say a particular IP/host has to be blacklisted, is there a way we could just enable it on the fly and avoid manual reboot by reconfiguring rate limit properties of Zuul api gateway service?

This library relies on Spring Boot's Autoconfiguration and its ability to refresh configuration on the fly.

Hi @marcosbarbero Thanks for you reply.

However, we're not using Spring Cloud Config Server and rather are fetching configuration properties from AWS SSM.

commented

As soon as you use a refresh strategy supported by Spring Boot, it will work using this project as well.
