Rafal Wojdyla commented on BEAM-1458:
-------------------------------------

Fyi - we have a first version of checkpoints in [Scio](https://github.com/spotify/scio) -
[checkpoint package](https://github.com/spotify/scio/blob/master/scio-extra/src/main/scala/com/spotify/scio/extra/checkpoint/package.scala).

> 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.
