-------------------------------
Summary: Add archive conflict resolution strategy to PutFile
Key: NIFI-9562
URL: https://issues.apache.org/jira/browse/NIFI-9562
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Mark Bean
Assignee: Mark Bean
The PutFile processor would benefit from an 'archive' Conflict Resolution
Strategy. This strategy is similar to 'replace'. However, if a file exists on
the file system and would otherwise be overwritten (or cause the FlowFile to
fail), the existing file is moved to an archive directory specified by the
processor's configuration.
The processor will add the following properties which depend on the replacement
strategy value of "archive" (new).
Archive Directory
Archive Filename Extension
Maximum Archive File Count
Guarantee Archive Filename Uniqueness
The processor will (optionally) add an extension to the filename when moving it
to the archive directory. If that filename is still not unique, the filename
can be made unique by adding a distinct value such as UUID. Similar to the
regular directory location for PutFile, the archive directory may also have a
limit on the total number of files it will hold.
