The write-ahead log (WAL) is everywhere. Yet, many people miss it and are not aware of it. The simple idea powers reliability in databases, messaging systems, and distributed systems. Let's discuss why it's important on the PostgreSQL, Kafka and MongoDB examples!
Oskar, you managed to write an article, a long one, about a topic that seemed to me easy but you showed me it was a superficial assumption đŸ˜€ That is a complete guide to WAL!
I definitely didn't want to scare you! đŸ˜… I didn't want to show that WAL is that hard, more that it's much more useful and widely used than it may seem. đŸ™‚
And a small notice as ukrainian citizen - I would think twice before donating anything to the army or anywhere at all. Average ukrainians don't have anything from this and probably have even more harm. Firstly, this is totally corrupted country and government, and any income motivate them to keep things as they are. And the second, which is even worse – a lot of donates later is used against peope, such cars and buses for the service which takes people forcibly into an army.
