Are there any limitations to the maximum size of a cluster currently?

I am trying to find out if there are any limits to how big a cockroach cluster can be and I can’t find much on it.

Does cockroach really just scale up in a linear fashion or does it start to tail off at some point?

Thanks

CockroachDB doesn’t have theoretical scaling limit. Your experience with scaling up varies and will generally depend on the hardware and the type of workloads that you are trying to run. CockroachDB Performance | CockroachDB Docs should give you some idea as to what we do to test performance and scalability.
