> When the source KTable is generated without the store name specified, the auto-generated store name use {{topic}} as the store name prefix. This would generate the store name as
> {code}
> Processor: KTABLE-SOURCE-0000000031 (stores: [windowed-node-countsSTATE-STORE-0000000029])
>       --> none
>       <-- KSTREAM-SOURCE-0000000030
> {code}
> We'd better improve the auto-generated store name as {{[topic-name]-STATE-STORE-suffix}}.
