On a site, every click on a product should be registered by a sales tracker: price, type, etc.

The sales tracker should provide an API so that complex queries can be performed, such as: Which products of a type "teapot" had a price below 20 EUR?


  • Recorded data should be available for querying no later than two hours after it has been recorded. For example, there are reports that Google Analytics may take up to 24h to update data. That is not acceptable.

  • Querying doesn't need to be fast, but recording does (of course).

Which sales tracker allows complex queries against collected data?
