Fluvio is streaming transport. And we built Stateful DataFlow on top of that for Stream Processing.
Arroyo is SQL first stream processing. Fluvio is streaming transport which can send data to Arroyo and there is an integration.
Stateful DataFlow and Arroyo are similar in the stream processing pattern and the use of Apache Arrow.
The interfaces are different. Fluvio and Stateful DataFlow support for SQL is the same dialect as columnar SQL supported by Polars. The Fluvio and Stateful DataFlow paradigm is more intricate more expressive and the platform is broader and deeper.
How would you say your project compares to Arroyo?
