>
> Currently, the min/max filter feature is turned off by default
> (MINMAX_FILTER_THRESHOLD=0).
> When joining into sorted columns in a fact Parquet table created by Imoala,
> the feature can be turned on by default. This is because Impala sorts the
> data in sort by columns in each data file during population. A min/max filter
> can be used to easily reject pages not overlapping with the search region
> specified in the filter.
