-------------------------------------
Summary: Add support for FileResourceService in PutFile
Key: NIFI-16159
URL: https://issues.apache.org/jira/browse/NIFI-16159
Project: Apache NiFi
Issue Type: Improvement
Reporter: Shubham Sharma
{{PutS3Object}} (NIFI-12642), {{PutGCSObject}} (NIFI-12643), and {{PutHDFS}}
(NIFI-12801) already let users pick the transfer source — either the incoming
FlowFile's content or a local file resolved through a {{FileResourceService}} —
via the standard {{Resource Transfer Source}} / {{File Resource Service}}
properties.
{{PutFile}} still writes only the FlowFile content. Users who want to stage a
local file to a directory on disk have to first pull it into a FlowFile with
{{FetchFile}} / {{{}GetFile{}}}, which is wasteful when the source is already a
path on the local filesystem (or reachable via a custom {{FileResourceService}}
implementation).
This ticket adds the same two properties to {{PutFile}} so it can:
* read from the incoming FlowFile content (existing default behavior —
unchanged), or
* read from a {{FileResourceService}} (new), streaming the resource straight
to the destination directory.
