> {noformat}
> {{rowIndexStride(0)}} makes {{StripeStatistics.getColumnStatistics()}} return 
> objects but with meaningless values, like min/max for 
> {{IntegerColumnStatistics}} set to MIN_LONG/MAX_LONG.
> This interferes with ability to infer min ROW_ID for a split but also creates 
> inefficient files.
