> There are several ways to organize immutable data durably that meet these requirements, the simplest of which is an append-only log.

This is also a fairly good way to handle large amounts of data with maximum performance on spinning rust, and at the heart of systems like Kafka.

I had assumed that the story would be very different with SSDs, so it's surprising to see append only logs show up again.

We haven't even started to discuss Object Storage, but it ends up looking very very similar if you're building data systems that use that instead of raw filesystems (not so much for physics reasons, but because of the way object storage require immutable objects and penalize you for many API calls)
