--------------------------------
Summary: With validation being performed asynchronously, updating
a processor causes validation to occur 3 times instead of once
Key: NIFI-5222
URL: https://issues.apache.org/jira/browse/NIFI-5222
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.7.0
Reporter: Mark Payne
Assignee: Mark Payne
With the merge of NIFI-950, we now have processors, controller services, and
reporting tasks being validated asynchronously. Each time that properties,
annotation data, or auto-terminated relationships are set, a task is kicked off
in the background to perform validation. Additionally, if any connections are
added/removed, it kicks off the task.
Right now, though, if a user clicks to configure a processor and then clicks
Apply, what happens on the back end is that we call setProperties(),
setAnnotationData(), and setAutoTerminatedRelationships() in the request. As a
result, we kick off validation 3 times. Instead, we should avoid kicking off
that background task until we've completed all updates to the
processor/controller service/reporting task. Then trigger validation only once.
