Documentation

data AggregateOperation

Specifies the set of parameters needed to perform aggregation in the aggregate transform.

See: newAggregateOperation smart constructor.

Constructors

AggregateOperation'

Fields

• column :: [Text]

  Specifies the column on the data set on which the aggregation function will be applied.

Arguments

:: AggFunction

$sel:aggFunc:AggregateOperation'

-> AggregateOperation

Create a value of AggregateOperation 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:column:AggregateOperation', aggregateOperation_column - Specifies the column on the data set on which the aggregation function will be applied.

$sel:aggFunc:AggregateOperation', aggregateOperation_aggFunc - Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop

aggregateOperation_column :: Lens' AggregateOperation [Text]

Specifies the column on the data set on which the aggregation function will be applied.

aggregateOperation_aggFunc :: Lens' AggregateOperation AggFunction

Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop
