What kind of data and amounts do you frequently encounter that is a good fit for relational storage but difficult to fit in a single server? Honestly curious.

It's not relational but key-value based, but I do need things like "update" operations, hence I can't use a simple blob store.

Thank you for taking the time to answer! IMNHO key-value can be a great fit for relational storage. But I'm still curious about what(why) and how much... Servers can grow pretty big these days.

And you say update... Across keys, or some keys depend on others? Otherwise it sounds like a perfect fit for sharding with reduced constraints/requirements.
