Confluent CCAAK Broker and Topic Config Guide

This chapter is about choosing the right configuration boundary. CCAAK regularly asks whether a behavior belongs at the broker level, topic level, or client level, and the right answer often depends on not mixing those layers together.

Compaction: Cleanup policy that keeps the latest value per key instead of full event history.

Log dir: Storage location used by a broker for partition data.
