The Buffer block will collect all incoming signals and emit them every interval. If interval_duration is non-zero, then the signal emitted each interval will be all the signals collected over the last interval_duration.
- backup_interval: An interval of time that specifies how often persisted data is saved.
- group_by: The signal attribute on the incoming signal whose values will be used to define groups on the outgoing signal.
- interval: Time interval at which signals are emitted.
- interval_duration: At each interval, emit signals collected during this amount of time. If unspecifed or 0, then all incoming signals collected during the last interval will be emitted.
- load_from_persistence: If
True, the block’s state will be saved when the block is stopped, and reloaded once the block is restarted. - signal_start: If
True, start the first interval when a signal is received.
- default: Any list of signals.
- default: Signals stored since the time specified by the interval_duration.
- emit: Emit stored signals immediately.
- groups: View information on current groups.
