Josh Harness updated SOLR-2851:
-------------------------------
Attachment: ArchivingFileDataSource.java
Custom file data source that archives files when the close method on the input
stream reader is called. Java package name is still specific to my company and
needs to be modified to reflect the apache structure. Also, tests are needed.
> Allow Data Import Handler to Archive Files After Processing
> -----------------------------------------------------------

> It would be great if, after processing flat files, DIH could place them in an
> archive folder so that other system processes could compress them, delete
> them, etc. We needed this feature, so I extended FileDataSource and decorated
> the InputStreamReader such that when the close method is called, the file is
> moved out of the way. This concrete implementation did exactly what I needed.
> However, a more correct textbook approach would involve refactoring
> FileListEntityProcessor such that it could take a configurable list of
> post-processing action policy/command classes so that the user could provide
> custom behavior that suits nearly any scenario (in a Chain of Responsibility
> style pattern). Nonetheless, I wanted to provide the suggestion, a basic
> one-off concrete implementation of archiving and start the discussion for
> where things might head in the future.
