By using these statistics, CBO improves query run plans and boosts the performance of queries run in Athena.

Case in point: circa 2002 I was teaching network security in a continuing education program. This is especially the case in data science; most enterprise organizations simply cannot hire enough of the data analytics talent they need therefore, so much of these staffing needs must be filled by current employees.
