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

The name of the transform node.

aggregate_inputs :: Lens' Aggregate (NonEmpty Text)

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

aggregate_groups :: Lens' Aggregate [[Text]]

Specifies the fields to group by.

aggregate_aggs :: Lens' Aggregate (NonEmpty AggregateOperation)

Specifies the aggregate functions to be performed on specified fields.
