Schedules#

There are two types of Schedule; bounded and unbounded. Any collection will be interpreted as a bounded schedule. Unbounded schedules are either cron expressions, or a pandas offset alias.

Bound schedules. These are always viable.

>>> import pandas
>>> schedule = ["2022-01-03", "2022-01-07", "2022-01-10", "2022-01-14"]
>>> another_schedule = pandas.date_range("2022-01-01", "2022-10-10")

Unbounded schedules. These must be made bounded by an available data argument.

>>> cron_schedule = "0 0 * * MON,FRI"  # Monday and friday at midnight
>>> offset_alias_schedule = "5d"  # Every 5 days

Bounded schedules are sometimes referred to as explicit schedules.
