Bucket4j + Infinispan: A Deep Dive Into Implementation

Bucket4j & Infinispan Integration

In distributed systems, the biggest challenge for rate limiting is state. How do you ensure that two parallel requests hitting different cluster nodes don’t “double‑spend” the same token?

In this article, we dive into the implementation details of the integration between the Bucket4j rate‑limiting framework and Embedded Infinispan (not HotRod). This setup creates a data grid across different pods of a single application, allowing for seamless, distributed token management.
