> In [this stream doc section|https://kafka.apache.org/11/documentation/streams/developer-guide/dsl-api#creating-source-streams-from-kafka],
 when reading records from Kafka to a global KTable, the doc says:
> `In the case of a GlobalKTable, the local GlobalKTable instance of every application
instance will be populated with data from only a *subset* of the partitions of the input topic.
Collectively, across all application instances, all input topic partitions are read and processed.`
> Is it correct? Each GlobalKTable instance only get assigned with a subset of the partitions
of the input topic? I remember it should be able to consume all the partitions of the input
topic.
