Our Goals

We made it lightweight and kept the efficiency in mind:

Self-contained

We ship a single dependency-free binary that runs on all Linux distributions
Fast to deploy, safe to operate

We are sysadmins, we know the value of operator-friendly software
Deploy everywhere on every machine

We do not have a dedicated backbone, and neither do you,
so we made software that run over the Internet across multiple datacenters
Highly resilient
to network failures, network latency, disk failures, sysadmin failures

In my previous post, I explained how a disk attached to a machine makes things difficult. Vertical scaling has its limits, and when you hit that limit, you can’t do horizontal scaling right away because of the attached disk. Mainstream databases like Postgres or MySQL don’t scale horizontally. I recently learned that BlueSky team switched from Postgres to a combination of Scylla and SQLite. One of the reasons was because (vanilla) Postgres is not horizontally scalable, but Scylla is.
