- groups :: [[Text]]
- aggs :: NonEmpty AggregateOperation
}
newAggregate :: Text -> NonEmpty Text -> NonEmpty AggregateOperation -> Aggregate

Documentation

data Aggregate Source #

Specifies a transform that groups rows by chosen fields and computes the aggregated value by specified function.

See: newAggregate smart constructor.

Constructors

Aggregate'
Fields name :: Text The name of the transform node. inputs :: NonEmpty Text Specifies the fields and rows to use as inputs for the aggregate transform. groups :: [[Text]] Specifies the fields to group by. aggs :: NonEmpty AggregateOperation Specifies the aggregate functions to be performed on specified fields.

Arguments

:: Text	`$sel:name:Aggregate'`
-> NonEmpty Text	`$sel:inputs:Aggregate'`
-> NonEmpty AggregateOperation	`$sel:aggs:Aggregate'`
-> Aggregate

Create a value of Aggregate 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:name:Aggregate', aggregate_name - The name of the transform node.

$sel:inputs:Aggregate', aggregate_inputs - Specifies the fields and rows to use as inputs for the aggregate transform.

$sel:groups:Aggregate', aggregate_groups - Specifies the fields to group by.

$sel:aggs:Aggregate', aggregate_aggs - Specifies the aggregate functions to be performed on specified fields.

aggregate_name :: Lens' Aggregate Text Source #

The name of the transform node.

aggregate_inputs :: Lens' Aggregate (NonEmpty Text) Source #

Specifies the fields and rows to use as inputs for the aggregate transform.

aggregate_groups :: Lens' Aggregate [[Text]] Source #

Specifies the fields to group by.

aggregate_aggs :: Lens' Aggregate (NonEmpty AggregateOperation) Source #

Specifies the aggregate functions to be performed on specified fields.
