----------------------------------
Summary: Add rolling restart / refresh
Key: NIFI-473
URL: https://issues.apache.org/jira/browse/NIFI-473
Project: Apache NiFi
Issue Type: New Feature
Reporter: Ricky Saltzer
For long running instances and clusters, it's sometimes required to switch out
custom NARs for new or updated processors. Currently, when you restart a NiFI
instance, processors that are on a timer driven schedule (e.g. 1 day, 1 week)
are executed, regardless of their schedule. This can be problematic if you're
dealing with datasets that shouldn't be pulled out of schedule.
It would be nice to have a rolling restart, or a refresh ability to load in new
NARs without re-executing all of the processors on the system. We could take
this one step further and have all processor schedules persisted somewhere, and
is read on start up.
