Histogram support in MySQL 8.0

In MySQL 8.0, you can create histograms over column values. Histograms will improve the selectivity estimates used by the query optimizer, especially for conditions on columns that are not indexed. This presentation will cover the types of histograms you can create, and discuss best practices for using histograms. The presentation will contain many practical examples of how histograms improve query execution plans.
