Logstash SQLite input without write permission to database

I have an SQLite database I'd like to read in real time, but I won't have write permissions to it.

From what I understand, the SQLite input plugin needs to create the equivalent of other input method's .sincedb files inside the database I'm trying to read. I could make a copy of the database to my own directory every so often, thus giving me write permission, but this would override the .sincedb equivalent and make Logstash reread all my data from the top, right? Is there a workaround to this?
