Anyone out there?
- CRDB talks Postgres Protocol and Dialect, TiDB talks Mysql Protocol and Dialect.
- TiDB is OLTP+OLAP, CRDB is OLTP only.
- CRDB is a single binary, TiDB has more moving parts/can be used in different ways.
I picked CockroachDB because it's Follow-the-workload and Interleaved tables included in their Community Edition, I'm a Postgres person so it was a natural fit. Also it's the little things, I made a comment in a closed issue and somebody paid attention in less than a day which makes me feel closer to them.
On the other hand, the fact that TiDB claims OLTP+OLAP feels like they're moving faster than CockroachLabs, PingCAP also says they have 25 companies using TiDB where CockroachLabs has less than 10 known study cases.
