There is a good chance that your proposed algorithm to enforce a uniqueness constraint in the application won't work.

Escher's unpopularity in high art circles is likely due to this improbable combination of uniqueness and popularity.

And you'll need that index whether you use the database or the application to enforce uniqueness.

Wouldn't a much more valuable conversation be about the apparent-but-perhaps-not-actual uniqueness of what Palantir does?

I get that its something more complex than a simple multicolumn uniqueness constraint, but not what it is supposed to do.

Since grammar has no reason to prefer large classification sets (generalization) to small (uniqueness), unlike descriptive linguistics, I'm perfectly happy to say that grammatically "the" is an article and leave it at that.

Uniqueness is irrelevant, it's the 100 million+ DAU's which are valuable.
