I think when people say "relational doesn't scale," what they mean is "MySQL often requires application-level changes to scale out."
I assume (among this crowd, anyway) that scaling out is more desirable vs. scaling up because the majority of the hardware costs are variable, whereas scaling up requires a step function of large cash investments that startups often can't afford.
Do those massive systems on Oracle etc scale out, or simply scale up with expensive hardware?

- fendale 15y agoYou can certainly scale out with Oracle RAC. At some point the bottleneck will likely be disk however, so buying a high end storage system would probably become priority.
