arroyo Difference between Arroyo and RisingWave

Thanks for your really cool library! I was wondering if you could make a brief overview of the main differences between Arroyo and RisingWave. From your blog, it seems that Arroyo doesn't store its own state on disk but in memory, so I guess it's not crash resilient, while RisingWave uses S3. Is that the main difference?

Hi @maelp , @devtyagi-c and @Mohan6677 , thanks for your asking.

As mentioned in https://github.com/timeplus-io/proton/issues/999

They have large use cases overlaps in streaming. Proton could go further regarding the functionality, perf, efficiency and stability; as well as in easy of operations in edge, on-prem, hybrid env. Historical processing, none of them can compete IMHO.

Having said this, looking forward to your real prod workload and compare if necessary.
