> Introduce CheckpointMetaData
> ----------------------------
>
> Key: FLINK-4730
> URL: https://issues.apache.org/jira/browse/FLINK-4730
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Reporter: Stefan Richter
> Assignee: Stefan Richter
> Fix For: 1.2.0
>
>
> Currently, the meta data for each checkpoint consists of up to 5 long values
> which are passed through several functions. When adding/removing meta data
> we would have to change function signatures in many places. Furthermore, this
> is prone to errors when the order of arguments is changed accidentally. We
> should introduce a CheckpointMetaData which encapsulates this checkpoint meta
> data.
