Cache management for rate limiting/throttling

We have an application that uses Bucket4j for throttling with Hazelcast as the backing in-memory data grid cache. Since Hazelcast is no longer supported as of Pega Infinity '25, we are looking for throttling on a low-latency caching solution that works across multiple (preferably on) specified node types. The release notes at Pegasystems Documentation mention Pega provides built-in alternatives. How can we use these built-in alternatives?
