This is daft. CockroachDB exhibits extremely strong isolation and consistency levels. I believe it is strictly serializable under most circumstances?

Also - anyone who says that x database must be rewritten “because GC” is just making an incredibly un nuanced argument about a nuanced problem. People have built production ready databases in both Java and Go. If you care about low/predictable tail latencies then you have a bunch of other more important problems to solve before you worry about the behaviour of a modern garbage collector. For example: how good is your cache hit ratio? How are your synchronous replication protocols affected by grey failures? That kind of thing.

I believe it only guarantees serializable isolation. You may get strict serializable, but it doesn’t appear to be the case that you will know for sure if any transactions were not linearizable.
