Yes, Franz, It’s Kafka
Let’s do a metamorphosis on your data. Don’t fear changing data.
You don’t need to be a brilliant writer to stream
data.
Franz Kafka was a German-speaking
Bohemian novelist and short-story writer,
widely regarded as one of the major figures of
20th-century literature. His work fuses
elements of realism and the fantastic.
