I'm trying to get the days_used column to count the distinct values in the dt column, so my days_used column should all be 4 instead of 1. Any help in changing the code? I'm hoping to just change the select structure for deriving days_used if possible. ...
Counting distinct values is a trivial matter with small datasets, but it gets dramatically harder for streams with millions of distinct points. Absolute counting accuracy can be attained through a set, but then you have the undesirable tradeoff of linear memory growth. What you really want when ...
