Kafka streams groupbykey

Was trying to understand how apache kafka stream handles the groupByKey operation internally. I get that while using groupby it creates internal repartition topics, but how does it manages unbounded data in groupByKey tranformation, had it been a windoweded operation(thus making the data bounded), i would have understood it, but that isn't that case as well.
