In some situations a Delta table may have stats collected which are not complete, for examble

  • CTAS a table, creates statistics (soon)
  • INSERT data with statistics disabled
  • INSERT data with statistics enabled

In this case to have complete stats a user would have to run the dropStats procedure and then re-analyze the data because the connector will ignore files older than the last analysis time. The procedure should have an argument to ignore it and analyze all files.
