> {{TopologyBuilderException}} is a pre-runtime exception that should only be 
> thrown beforeĀ {{KafkaStreams#start()}} is called.
> However, we do throw {{TopologyBuilderException}} within
>  - `SourceNodeFactory#getTopics`
>  - `ProcessorContextImpl#getStateStore`
>  - `StreamPartitionAssignor#prepareTopic `
> (and maybe somewhere else: we should double check if there are other places 
> in the code like those).
> We should replace those exception with either {{StreamsException}} or with a 
> new exception type.
