>          Issue Type: Bug
>            Reporter: Thomas Weise
>            Priority: Minor
>
> No inputs received, empty maps produced. The operator is probably only used in demos, and that's how the issue was noticed. Word count result files filled with just {}s. The suggested solution is to change the operator to only emit non-empty results.
