Talk Info:
Databases are awful. They lose information, corrupt state, and do other terrible things, both by design and by accident. You’d think that *testing* databases to see how awful they are would help make them better, but it turns out that testing most of the useful database safety properties is *also* awful. We came up with a better way to test databases, called Elle. Elle finds, graphs, and explains a wealth of isolation violations by mapping observed histories to Adya-style dependency graphs, and does so in linear time. Come learn the one weird trick that BIG DATA, SIGMOD, and VLDB don’t want you to know!
