> -------------------------------------------------------
>
> Key: FLINK-20453
> URL: https://issues.apache.org/jira/browse/FLINK-20453
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Environment: *
> Reporter: Roman Khachatryan
> Priority: Minor
> Fix For: 1.13.0
>
>
> The following classes handle with checkpointing in a subtask:
> - 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:
> * org.apache.flink.streaming.runtime.tasks (existing)
> * org.apache.flink.streaming.runtime.tasks.checkpointing (proposed)
> * org.apache.flink.streaming.runtime.checkpointing (proposed)
> Another class that could me moved is SubtaskCheckpointCoordinator(Impl).
>
> This should be done after FLINK-19681 to avoid conflicts.
