only.Expand description
ColumnPageStatistics
contains the minimum, maximum, and null_count
of each page of a parquet column, as an Array
.
This struct has the following invariants:
min
,max
andnull_count
have the same length (equal to the number of pages in the column)min
,max
andnull_count
are guaranteed to be non-nullmin
andmax
have the same logical type
Fields
min: Box<dyn Array>
The minimum values in the pages
max: Box<dyn Array>
The maximum values in the pages
null_count: UInt64Array
The number of null values in the pages.
