-----------------------------------
Summary: Add a command to NiFi CLI to expose all Flow snapshots
using PersistenceProvider
Key: NIFI-5076
URL: https://issues.apache.org/jira/browse/NIFI-5076
Project: Apache NiFi
Issue Type: Improvement
Components: Tools and Build
Reporter: Koji Kawamura
Assignee: Koji Kawamura
In NiFi Registry project, there is an improvement to add new
FlowPersistenceProvider which can utilize Git technology.
We need to provide a tool to migrate existing Flow snapshots those are
persisted with the FileSystemFlowPersistenceProvider, so that users can switch
from that to new Git persistence provider, or vise versa.
A possible approach is taking a providers.xml file and a URL of running NiFi
Registry with a FlowPersistenceProvider which is currently used, then extract
all Flow snapshots then persist those with the new PersistenceProvider. This
way, existing Flow snapshots can be extracted into the new PersistenceProvider
storage. After that, NiFi Registry can be configured to use new provider with
existing Flow snapshots.
