tff.program.PeriodicReleaseManager

A tff.program.ReleaseManager that releases values at regular intervals.

Inherits From: ReleaseManager

A tff.program.PeriodicReleaseManager is a utility for releasing values at regular intervals and is used to release values from platform storage to customer storage in a federated program.

The interval can be controlled at construction time by setting the periodicity. The periodicity can be a positive integer or datetime.timedelta. A periodicity of 3 means that every third value is released to the release_manager, and invoking release ten times will release the third, sixth, and ninth values. A periodicity of datetime.timedelta(hours=3) means that three hours after the previously released value the next value is released to the release_manager.

release_manager A tff.program.ReleaseManager used to release values to.
periodicity The interval to release values. Must be a positive integer or datetime.timedelta.

ValueError If periodicity is not a positive integer or datetime.timedelta.
