Kenneth Knowles commented on BEAM-1458:
---------------------------------------
I would suggest we consider checkpoint migration/conversion mechanisms as a
core part of the design.
> Checkpoint support in Beam
> --------------------------
>
> Key: BEAM-1458
> URL: https://issues.apache.org/jira/browse/BEAM-1458
> Project: Beam
> Issue Type: Improvement
> Components: beam-model
> Affects Versions: 0.5.0
> Reporter: Rafal Wojdyla
> Labels: features
>
> Beam could support checkpoints - similar to:
> * flink's snapshots
> * scalding's checkpoints
> Checkpoint should provides a simple mechanism to read and write intermediate
> results. It would be useful for debugging one part of a long flow, when you
> would otherwise have to run many steps to get to the one you care about.
