Transactional writes are likely the slowest thing since they need to talk to all replicas.

- elvinyung 9y agoActually hmm, do reads need to talk to all replicas in this case (serializable isolation)?
- ComputerGuru 9y agoAs I understand it, reads only need to talk to the lease owner, which in turn bypasses raft since write consensus guarantees atomicity of after completion of write intents. Cockroach tries best-effort to have the lease owner and the raft leader be the same.
