---------------------------------------------------------------

Recommendation from my side to leave this feature out.

The natural kappa architecture is to re-bootstrap all state from kafka if 
necessary from the beginning. Thats were most of the simplicity of this 
architecture comes from. Implementing such a side kick will just increase 
complexity by a whole lot because its yet another fight against the 
architecture.

So i hope we can withstand the itchyness of a ticket being there and let  the 
project benefit from leaving this out.

Also: Isn't that why kafka supports microservices so well, people could just 
run flink as a separate consumer

> Apache Flink has a feature called 
> [savepoints|https://ci.apache.org/projects/flink/flink-docs-stable/ops/state/savepoints.html]
>  which gives possibility to reset stream processing topology state to 
> specific point in time. Similar feature can be useful for Kafka Streams 
> applications as well.
