Have you considered doing some restructuring of the _onTrigger()_ method?
Since the packaging format is based on the processor wide configuration
property (not FlowFile) most of the logic (switch/case) could be performed once
instead of every time _onTrigger()_ is called. That includes the new logic with
regex pattern compile.
Or am I missing something big here?

> There are times where you may want to only extract a portion of an archive,
> such as a specific folder, or perhaps a specific file. Similar to how the
> {{GetFile}} processor works, we should provide a property ({{File Filter}})
> which by default extracts all files. The user can modify this property to
> extract only files they wish to process downstream.
