State migration scenario's

[Marlo Ploemen]

Hi community,
 
I am looking into the data migration and schema evolution process for stateful 
streaming jobs. Currently, there is no orchestration support for performing 
these job evolutions and no in-job state migration or schema evolution syntax 
(as this is part of the separate state processor API). I am looking for 
examples (e.g. Github repositories) or scenarios of stateful streaming jobs 
where the orchestration of their state evolution process can improve 
development quality.
 
Best, Marlo
