Note that the "databases" above are logical databases, not database hosts.
- pcthrowaway 5y agoSo according to this usage, one database instance with a few databases would be a cluster?
- throwaway894345 5y agoI'm not an expert, but as far as I can tell, even a single database instance with a single database (or maybe no databases at all?) could constitute a "cluster".
- snthpy 5y agoThank you for this. I didn't realise this and for the past few years have been thinking that I seem to be the only one that runs only a single database host as everyone else seems to have "clusters". I never realised this just means multiple databases.
