I am trying to evaluate druid for building an application that supports what-if analysis support to users. This co-relates closed with excel kind of functionality where changing a value in one cell triggers changes in other cell values. In our case we would have multiple rows in various tables getting updated when the user changes a row value. The response needs to be in real-time or near real-time.
Does Druid fit such an use-case? If so, what would be some of initial steps to evaluate druid for this use case?
