-----------------------------------------
Summary: Unannounced change to flow.json.gz
Key: NIFI-10016
URL: https://issues.apache.org/jira/browse/NIFI-10016
Project: Apache NiFi
Issue Type: Bug
Components: Configuration, Core Framework
Affects Versions: 1.16.1, 1.16.0
Reporter: Daniel Salwerowicz
Attachments: 2022-05-11--12-35-22.png, 2022-05-11--12-37-29.png
As far as I am aware there is no information anywhere that flow.xml.gz is now
being replaced by flow.json.gz.
While it might not be that big of a deal to some I was very concerned that
neither changelog, nor migration guide from 1.15 to 1.16 mention that this has
occurred.
The only way I noticed that was because during update I needed to look up
something in nifi.properties file and noticed a configuration option for
flow.json.gz.
This lead me to search for what it is, when the change happened etc.
The only place in documentation where I can see flow.json.gz being mentioned is
in the Admin Guide, which itself pulled a move comparable to ministry of truth
from 1984 and just acts like flow.json.gz was always used in NiFi, no mention
about change or what to do with old flow.xml.gz files.
I think that both changelog and migration guide should at the very least
mention that switch to flow.json.gz has occured, why it happened, and how to
deal with old flow.xml.gz when upgrading.
If I am wrong and there is mention of flow.json.gz anywhere in the official
channels, then I apologize, and ask for link to them so I can read more.
It was very surprising to come across it when I wasn't expecting it after
reading both changelog and migration guide.
