C++ Logging: Async vs Sync

What are the main differences between async and sync logging in C++?

Async logging allows logging operations to be performed in a separate thread, improving performance, while sync logging writes logs immediately, ensuring data integrity but potentially slowing down the application.

When should I use async logging over sync logging?

Use async logging when performance is critical and you can tolerate some delay in log writing. Sync logging is better for critical applications where every log entry must be recorded immediately.

Are there any downsides to async logging?

Yes, async logging can lead to data loss if the application crashes before the logs are flushed. It also adds complexity to the logging system.

Can you give me an example of how to implement async logging in C++?

Sure! You can use libraries like Boost.Log or spdlog, which provide built-in support for async logging. Would you like a code snippet?
