I vote for dropping spaces from the filename. Yes, it's technically valid,
but it's escaped differently on different OSes and will just cause problems.
There is no harm in removing it.
> Add Git backed persistence provider
> -----------------------------------
>
> Key: NIFIREG-162
> URL: https://issues.apache.org/jira/browse/NIFIREG-162
> Project: NiFi Registry
> Issue Type: Improvement
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
> Priority: Major
>
> Currently, NiFi Registry provides FileSystemFlowPersistenceProvider, which
> stores Flow snapshot files into local file system. It simply manages snapshot
> versions by creating directories with version numbers.
> While it works, there are also demands for using Git as a version control and
> persistence mechanism.
> A Git backend persistence repository would be beneficial in following aspects:
> * Git is a SCM (Source Control Management) that manages commits, branches,
> file diffs, patches natively and provide ways to contribute and apply changes
> among users
> * Local and remote Git repositories can construct a distributed reliable
> storage
> * There are several Git repository services on the internet which can be used
> as remote Git repositories those can be used as backup storages
> There are few things with current NiFi Registry framework and existing
> FileSystemFlowPersistenceProvider those may not be Git friendly:
> * Bucket id and Flow id are UUID and not recognizable by human, if those
> files have human readable names, many Git commands and tools can be used
> easier.
> * Current serialized Flow snapshots are binary files having header bytes and
> XML encoded flow contents. If those are pure ASCII format, Git can provide
> better diffs among commits, that can provide better UX in terms of
> controlling Flow snapshot versions
> * NiFi Registry userid which can be used as author in Git commit is not
> available in FlowSnapshotContext
> Also, if we are going to add another Persistence Provider implementation, we
> also need to provide a way to migrate existing persisted files so that those
> can be used by new one.
