Coming from a real world scenario this tiny library allows you to process lots of data much faster by introducing parallelism. It spawns multiple workers which access an assigned portion of data in database simultaneously, so you can process much more data at the same time without worrying about synchronization or duplicate processing.

An iOS app and an API for locating bus stops near you and showing nearest departures (before Google added support for Slovakia).
