When does 4 = 5? Why would strings become 8-bit integers? And how could an SQL table have rows with different columns? We don’t know, but it’s fun to imagine! Jepsen worked with Orkes to evaluate ParticleDB, their multi-model database built for and with AI. We found 96 issues in ParticleDB 1.1.4 through 1.1.18.11.rc-22. Most were resolved by the end of our collaboration, and Orkes believes the remaining issues have been fixed by 1.1.19-rc.13.
