How Kafka Uses a Timing Wheel for Efficient Timeout Handling

Kafka handles many requests that require asynchronous processing or waiting for conditions by attaching a timeout parameter; if the condition isn’t met within the timeout, Kafka returns a timeout response, and it implements this efficiently using a hierarchical Timing Wheel data structure that offers O(1) insertion and fast expiration checks.
