It's not, not at all. We've actually gone as far as replacing RocksDB with https://github.com/cockroachdb/pebble/ by default now (and it's written in Go).

I have no idea what you're saying. What's a "row-oriented storage" if not storing all the column values of a row in sequence, in contrast to storing all the values in a column across the table in sequence (aka "colu

We take our claims if correctness very seriously. The behavior you're describing, depending on exactly what you're doing, is likely an allowed serializable history, which is the isolation level we claim to support. See [0] for a d
