morpheus.utils.column_info.DistinctIncrementColumn

class DistinctIncrementColumn(name, dtype, input_name, groupby_column='username', period='D', timestamp_column='timestamp')[source]

Bases: morpheus.utils.column_info.RenameColumn

Subclass of RenameColumn, counts the unique occurrences of a value in groupby_column over a specific time window period based on dates in the timestamp_column field. Only increments the count when the value in input_name changes.

Attributes

groupby_columnstr: The column to group by.
periodstr: The period to use when grouping.
timestamp_columnstr: The column to use for determining the period.

Methods

`convert_pandas_dtype`(dtype)	Return the pandas type string of column.
`get_input_column_types`()	Return a dictionary of input column names and types needed for processing.
`get_pandas_dtype`()	Return the pandas type string for the currently set `dtype`.

static convert_pandas_dtype(dtype)[source]

Return the pandas type string of column.

get_input_column_types()[source]

Return a dictionary of input column names and types needed for processing. This is used for schema validation and should be overridden by subclasses.

get_pandas_dtype()[source]

Return the pandas type string for the currently set dtype.
