Arguments

:: Natural	`$sel:maximumLength:StringColumnStatisticsData'`
-> Double	`$sel:averageLength:StringColumnStatisticsData'`
-> Natural	`$sel:numberOfNulls:StringColumnStatisticsData'`
-> Natural	`$sel:numberOfDistinctValues:StringColumnStatisticsData'`
-> StringColumnStatisticsData

Create a value of StringColumnStatisticsData with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:maximumLength:StringColumnStatisticsData', stringColumnStatisticsData_maximumLength - The size of the longest string in the column.

$sel:averageLength:StringColumnStatisticsData', stringColumnStatisticsData_averageLength - The average string length in the column.

$sel:numberOfNulls:StringColumnStatisticsData', stringColumnStatisticsData_numberOfNulls - The number of null values in the column.

$sel:numberOfDistinctValues:StringColumnStatisticsData', stringColumnStatisticsData_numberOfDistinctValues - The number of distinct values in a column.

stringColumnStatisticsData_maximumLength :: Lens' StringColumnStatisticsData Natural Source #

The size of the longest string in the column.

stringColumnStatisticsData_averageLength :: Lens' StringColumnStatisticsData Double Source #

The average string length in the column.

stringColumnStatisticsData_numberOfNulls :: Lens' StringColumnStatisticsData Natural Source #

The number of null values in the column.

stringColumnStatisticsData_numberOfDistinctValues :: Lens' StringColumnStatisticsData Natural Source #

The number of distinct values in a column.
