How do I use Redis to implement rate-limiting across multiple Spring Boot instances with varying quotas

Question

Can you tell me how to use Redis to implement rate-limiting across multiple spring boot instance with varying quotas?

Answer 1

You can use Redis to implement distributed rate-limiting across multiple Spring Boot instances by leveraging Redis' atomic operations. The steps are as follows:

• Add Redis Dependency:
• Service Implementation:
• Controller Usage:

Here is the code snippet showing all these steps:

In the above code, we are using ZSET Usage, which Redis ZSET tracks the timestamps of requests for each user, Window Quota, which limits user requests within a rolling time window (e.g., 1 minute) and Distributed Lock-Free to Efficiently for distributed rate-limiting across multiple Spring Boot instances.

Hence, using this, you can implement rate-limiting across multiple Spring Boot instances with varying quotas
