CockroachDB 2.0 Performance Makes Significant Strides
Looks very promising! We've looked at Cockroach for a particular project, and we've been concerned that performance wasn't good enough.Cockroach performance seems to scale linearly, but single-connection performance, especially for small transactions, seems rather dismal. Some casual stress testing against a 3-node cluster on Kubernetes showed that small transactions modifying a single row could take as much as 7-8 seconds, where Postgres would take just a few milliseconds.The documentation recommends that you batch as many updates as possible, but obviously that doesn't work for low-latency applications like web frontends that need to be able to do small, fine-grained modifications.
