The Data Profiling feature was first added to public preview just under a year ago in November 2018. Then it went GA in May 2019 and just 5 months later, they’ve added more goodness. That’s one of the great things about Power BI, the release cadence. If you don’t like something or want more features, just wait a few months (or five in this case).
One of the big things that was lacking with the Data Profiling feature was the text length statistics. This is a huge deal for me. It’s one of the things that I’ve encounter most frequently, incorrectly sized string columns in data warehouses. Well, the wait is over, text lengths are now available. Unfortunately, it’s not intuitive on how to get them.
Sounds like there’s still room for further improvement, but this is a positive step.
