Description

Describe the bug
Downloading results of an aggregation query as csv from the web console triggers the aggregation query to be run again by the server before sending the data. This is inefficient when the whole result set is already displayed and known (for example 1 billion data points aggregated into a 10-row result-set).

Expected behavior
When results are sent to the console, a query should not be run again before sending csv results.

Research direction

Start in the web console's CSV download flow and trace how aggregation results are requested and exported. Compare the export path with the already displayed result set; done means downloading CSV sends the existing results without running the aggregation query again.
