@Deprecated
public interface Bucketer
extends Serializable

A bucketer is used with a RollingSink to put emitted elements into rolling files.

The RollingSink has one active bucket that it is writing to at a time. Whenever a new element arrives it will ask the Bucketer if a new bucket should be started and the old one closed. The Bucketer can, for example, decide to start new buckets based on system time.
