> When state store instances that are logging-backed are initialized, we need to check if the corresponding change log topics have been created with the right number of partitions:
> 1) If not exist, create topic
> 2) If expected #.partitions < actual #.partitions, delete and re-create topic.
> 3) If expected #.partitions > actual #.partitions, add partitions.
