Hi Dorian,
In general, CockroachDB is designed to support thousands of nodes, and there are no hard limits in terms of max nodes, max storage per node, max columns in a table, etc. There may be limits in practice, though. For example, all table metadata is currently held in memory, so you don’t want to have too many tables. As we get closer to production readiness, we'll be doing larger scale tests that will let us discover the practical limits of the system, and we'll be sure to document those.
Best,
Jesse
So::
1. max number of nodes in a cluster (ex: rethinkdb supports up to ideally 20)
1.1. Does the scalability increase by 1 with each node (assuming even usage on all ranges) or something <1 like in postgresql-xl ?
2. max storage per node (some kind of limit on the lower storage layer, ex like pg has)
3. max rows/kv per node/range/table
4. max number of columns in a table (ex: we store column-id as 1-byte so 256 max or something similar)
5. max number of tables (ex: more than x tables it's an antipattern since each table has overhead in ram)
6. max number of ranges (each range has overhead, does each node know the position of each range, or only range.ranges?)
These I think should also be in the faq/docs ?
