В сущности, Kafka хранит все свои сообщения на диске
First, some background: both persistent and transient messages can be written to disk. Persistent messages will be written to disk as soon as they reach the queue, while transient messages will be written to disk only so that they can be evicted from memory while under memory pressure. Persistent messages are also kept in memory when possible and only evicted from memory under memory pressure. The "persistence layer" refers to the mechanism used to store messages of both types to disk.
