Hi!
How often does *exactly* the same query get run within 2 minutes ?
Depends where the query is coming from. E.g. if there's a graph backed by query, then a lot of people can be seeing the graph and running a query. Same if somebody publishes a link to some query e.g. during a talk or in article and a bunch of people come to look at it. Depends on use case. Some use cases - like graphs - we are just planning, so we can't really rely on statistics here.
I'd guess there's probably only a very few queries like that though.
Well, maybe - we don't really know yet. That's why I want to hear opinions on this :)
