The problem
Teams lose days moving data into a warehouse before they can answer a question. By the time the copy is ready, it is stale — and the original systems still need to be maintained.
The River approach
River plans each part of a query and pushes work down to the source that owns the data, combining the results in one transparent execution plan.
