+This connector provides a Sink that writes partitioned files to filesystems
+supported by the Flink `FileSystem` abstraction. Since in streaming the input
+is potentially infinite, the streaming file sink writes data into buckets. The
+bucketing behaviour is configurable but a useful default is time-based
+bucketing where we start writing a new bucket every hour and thus get
+individual files that each contain a part of the infinite output stream.
+Within a bucket, we further split the output into smaller part files based on a
+rolling policy. This is useful to prevent individual bucket files from getting
+too big. This is also configurable but the default policy rolls files based on
+file size and a timeout, i.e if no new data was written to a part file. 
+#### Usage
+The only required configuration are the base path were we want to output our
+data and an
