lisa.datautils.series_update_duplicates(series, func=None)

Update a given series to avoid duplicated values.

Parameters:

• series (pandas.Series) – Series to act on.

• func (collections.abc.Callable or None) – The function used to update the column. It must take a pandas.Series of duplicated entries to update as parameters, and return a new pandas.Series. The function will be called as long as there are remaining duplicates. If None, the column is assumed to be floating point number of seconds and will be updated so that the no duplicated timestamps exist once translated to an integer number of nanoseconds.
