Description

The goal is to prevent the main application thread (e.g., the one handling network requests) from blocking on slow disk I/O, while guaranteeing that writes are ordered and durable.

For replicated logs, the producer-consumer pattern with a dedicated writer thread is the standard and safest approach.

Producers: Your application's main threads (the "producers") receive log entries. Instead of writing to the file themselves, they just place the log entry into a thread-safe, in-memory queue. This is a very fast operation, so the main thread is immediately free to handle the next task.

Dedicated Writer: A single, separate background thread (the "consumer" or "writer") continuously pulls log entries from the queue. This is the only thread that ever touches the file. It writes the entries to the log file sequentially.
