   "description": "The regular COUNT(DISTINCT ...) always performs a regular sort internally, which results in bad performance if there's a lot of duplicate values. This extension implements custom count_distinct aggregate function that uses an optimized sorted set to achieve the same purpose. The extension currently supports only data types passed by value",
