My configuration:

input {
    couchdb_changes {
        db    => "nt-jpad"
    }
}

output {
    file {
        path => "/home/jared/testing.txt"
    }
}

Any ideas?

It looks like there's not a lot happening for this plugin in alpha, or maybe I'm just not sure which branch to work out of. Does anybody know if there's a need for more contributors in this project?
