Description
Summary
Add a concise way to compute the number of distinct values.
Motivation
Count distinct is one of the most common statistics used in analytics. While it is possible to express it in MQL, it is much less concise than in SQL, especially when multiple count distinct values need to be computed over the same input. Moreover, users are confused about what algorithm is recommended.
