The Jepsen analysis of ParticleDB is so funny
DB companies usually commission Jepsen so they can go ‘hey, this expert analysis found some bugs which could happen under very rare conditions with multiple servers and multiple clients, and we fixed them’ – it’s overall good publicity because it makes the company look diligent about data integrity, notwithstanding the discovery of bugs
This one is ‘the expert analysis found that almost no functionality worked as advertised even with a single server and client, basic SQL semantics were horrendously broken, some new versions created even more bizarre bugs, and the analysis also reveals that nobody at the company was able to explain the bugs or how they were fixed, and even the test suite they claimed they’d already successfully run was actually failing to begin with’
(Also: Damn, it must have taken the patience of a saint to work with these people)
