The main idea (agenda) of the report is:
1) What is rate-limiting and where and for what you need to use it
2) Main algorithms for rate-limiting: Token Bucket vs Leaky Bucket
3) Advantages and disadvantages of using Token Bucket: less memory to use for your cache (pros); Burst problem if you using Bucket for not long-time distance (cons)
4) Main implementation of rate-limiting: Resilience4j, Google Guava, Bucket4j - comparison
5) Why Bucket4j: main features implemented in the library
6) Simple code example
7) Distributed code examples based on in-memory distributed cache: Redis, Dynamo, JSR107 cache (Hazelcast, Apache Ignite, Oracle Coherence)
