DESCRIPTION

Jepsen is a tool for testing databases, combining fault injection, generative testing, and sophisticated safety checkers to find concurrency bugs and availability issues. We worked with the Scylla team to identify multiple safety issues in Scylla's lightweight transactions (LWT) layer, including split-brain behavior and write loss in healthy clusters. In this talk, we'll discuss testing techniques more generally, and what we found (and what was fixed!) in ScyllaDB.
