> - AlignedController
> - AlternatingController
> - CheckpointBarrierBehaviourController
> - CheckpointBarrierHandler
> - CheckpointBarrierTracker
> - SingleCheckpointBarrierHandler
> - UnalignedController
> They all reside in package org.apache.flink.streaming.runtime.io;
> Other classes in this package include e.g. RecordWriterOutput, PushingAsyncDataInput

> A better place could be:
