public class ProcTimeMiniBatchAssignerOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<BaseRow>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<BaseRow,BaseRow>, org.apache.flink.streaming.runtime.tasks.ProcessingTimeCallback

A stream operator that emits mini-batch marker in a given period. This mini-batch assigner works in processing time, which means the mini-batch marker is generated in the given period using the processing time. The downstream operators will trigger mini-batch once the received mini-batch id advanced.

NOTE: currently, we use Watermark to represents the mini-batch marker.

The difference between this operator and RowTimeMiniBatchAssginerOperator is that, this operator generates watermarks by itself using processing time, but the other forwards watermarks from upstream.
