Feature Request

Is your feature request related to a problem? Please describe:

Two data found during test.
When we analyze a table with 60 million rows and about 10 columns(with indexes), it costs 59s.
When we analyze a table with 10 million rows and about 369 columns(with indexes), it costs 3min.

Describe alternatives you've considered:
