Yandex ClickHouse also should be on the list!

No pricing and no self-hosting option (either/or would be fine of course). A pretty neat tool for hobbies, maybe...

MongoDB is not well suited for OLAP-style workloads - have you considered Yandex ClickHouse?

404 not found at the moment - does anyone has a snapshot?

edit: nevermind, it is available again - weird

To be fair, Spark is way too slow to be used as a back-end database system (there's a big bap between "lightning speed computation", as they put them, and a common workload for a database serving data to a user-facing application).

Now of course Spark makes up for it with its great flexibility and scalability, but I do not really see the two technologies as competing ones.

This even without getting into the other parts of the data model (insert, update, delete) that do not exist in Spark (or "kind of" exist), by design.

Honestly I don't know, I do not work for Thoughtspot.

My assumption is that it works on metadata coming from a relational schema with a rule parser on top.

Honestly I don't see how it would work well enough if it was based on NLP of unstructured data.

I have tried it ~1 month ago and was quite a bit underwhelmed - direct connectivity with Google products is nice, but the data manipulation capabilities themselves lag behind Tableau a big deal (especially when it comes to clicking around in charts and tables to slice your dataset, which is admittedly something in which Tableau excels).

I do believe it is a valuable addition to the GA enterprise tier (especially for customers savvy enough to use BigQuery too), but at the moment I don't quite see it as a serious competitor to other off-the-shelf BI tools - would be very happy to be proved wrong in a few months, though.

What about Selenium? Is it already covered in point 2?

There, I've saved you from reading the article.
