Join our Community in its new Home - The Datorama Trailblazer Community Group!

It's been an amazing 3 years coming together in this forum to collaborate, innovate, support, and inspire each other about our shared usage of Datorama. While this is not quite a goodbye, we are excited to announce that we are getting a fresh start in our new home within the Salesforce Trailblazer Community. We have a ton of fun new content planned and you may even see the revival of some of our most popular posts from the past few years.

We’ll be keeping this group around for a bit for you to peruse, but as of November 15, we will no longer be allowing new posts or comments. Be sure to join our new group at to keep the conversation going.

We can’t wait to see you there!

Datorama Riddle #6: Will the deal be closed?

The Prime Number Array (PNA) space observatory in New Mexico has 7 huge state-of the-art radio telescopes, all working together as a single unit, designed to study the universe and its darkest secrets. Covering the skies with an astonishing resolution of 0.0001111 of 1 degree (or 0.04 of an arcsecond) at each interval, the observatory is capable of detecting the light emitted by the burning flame of a single candle on the surface of the moon (not that one can ever be lit there without oxygen).  

This massive electronic sky-scanner creates tens of thousands of images and records millions of objects, generating terabytes of data on a daily basis. The PNA is pushing its computing power to its limits in trying to cope with its ever-growing tsunami of data output and decides it’s time to consider other solutions. There are three main challenges the alternative solution will have to address:

  1. Unlimited storage space that can dynamically scale.

  2. An effective way to harmonize all the collected data as well as easily visualize some of its selected findings when needed.

  3. As it is mainly used for research by education bodies worldwide, it must allow for the data to be queried using a recognized querying language and must not charge per query.  

The Datorama Data Lake can easily rise to the challenge on all of these fronts. In studying how the observatory works for the purpose of accurately scoping the implementation process, the Sales Engineers learn the following:

To generate 3D images of an observed object or event, the telescopes always join forces and operate in clusters of three. However, it is unknown in advance which 3 will be eventually selected for every scan, as it simply depends on the telescopes that happen to be at the best angle for the required observation and that are also available at that very moment.   

To hit the ground running, PNA have asked that for each possible cluster, they’ll have a ready-to-use query available in the lake’s query library, as part of the implementation process, which itself is predicted to last 6 months. The Sales Engineers know that they’ll be unable to commit the Implementation team to more than 6 queries a month, but that otherwise it’s a sure win. 

Given that the order of the selected telescopes within the cluster doesn’t matter, can you tell if the deal will be closed or not? Please provide calculations to support your answer.
