I think there is a good argument for introducing a new function which degrades to hll at a threshold (which the user could even supply). My expectation of distinct count is that it is exact if it produces a result, degrading to an approximate result without being explicit about it makes query results hard to reason about. Degradation to an approximate result at an arbitrary threshold is arguably worse than always producing an approximate result. -- This is an automated message from the Apache Git Service.
