>A database that crashes should not be corrupt!!! Isn't this reliability 101? Why doesn't myrocks have chaos monkey stress testing etc etc?
Because Facebook has little incentive to ensure that RocksDB works well in your use case. MyRocks was built for Facebook and anything that Facebook doesn’t do probably isn’t particularly hardened. They aren’t going to invest time doing chaos monkey stress testing on codepaths they don’t use. Things like durability might not be super important to them because they will make it up in redundancy.
I remember being burned by something similar during the early days of Cassandra. I’m sure Cockroach has hit the same bugs.
