Describe the enhancement requested

Column statistics are mostly used for accelerating row filtering, while not all the columns are used in a query predicate. For example, the binary columns are not often used in filtering. However, they need many CPU/memory resources for the statistics calculate and store. We could add the configuration to support enabling/disabling the specified column statistics. This could reduce the footer size as well.
