class CountAggregator[source]#

Bases: Aggregator

Returns the count of non-null values in the look window.

name: str = 'count'#

output_type#: alias of int

class EarliestAggregator(timestamp_col_name: str, name: str = 'earliest')[source]#

Bases: Aggregator

Returns the earliest value in the look window.

Returns the slope (i.e. the correlation between the timestamp and the value) in the look window.

name: str#

output_type#: alias of float

timestamp_col_name: str#

class SumAggregator[source]#

Bases: Aggregator

Returns the sum of all values in the look window.

name: str = 'sum'#
