Why local disk? What would be gain by that compared to using StandbyTasks?

> Labels: need-kip, streams
>
> The parent ticket is KAFKA-3184.
> The goal of this ticket is to provide a general snapshotting API for state
> stores in Streams (not only for in-memory but also for persistent stores),
> where the snapshot location can be either local disks or remote storage.
> Design scope is primarily on:
> # the API design for both checkpointing as well as loading checkpoints into
> the local state stores
> # the mechanism of the checkpointing, e.g. whether it should be async?
> whether it should be executed on separate threads? etc.
