The pulse_id stream can be used to synchronize components.
For example, the writer can listen for the current pulse_id
and write with 1 second delay to a file. This will help us
eliminate the need to wait for the run to complete to start
the data write request.
Since processing of live data can be done at 100Hz it would
be more difficult to stream the full rate with a PUB/SUB mode.
To support distributed live analysis we move to PUSH/PULL
model, since we can support only one live processing at a time
anyway (network constraints when working with large detectors).
