----------------------------------
Summary: Framework should use FlowManager.findAllConnections()
when available
Key: NIFI-7087
URL: https://issues.apache.org/jira/browse/NIFI-7087
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Matt Burgess
Many places in the framework the entire list of Connections is needed, and
sometimes the list is assembled by recursively collecting all the Connections
for each child process group. This can be an expensive operation, especially
since FlowManager keeps a Set of all Connections. It is noticeable in
ConnectionStatusAnalytics for example.
Whenever a FlowManager object is available to a class that retrieves all
Connections, it should use FlowManager.findAllConnections() rather than
rootGroup.findAllConnections().
