Never tried it, but looks promising

As someone who myself worked on a hobby-level Rust based Kafka alternative that used Raft for metadata coordination for ~8 months: nice work!

Wasn't immediately clear to me if the data-plane level replication also happens through Raft or something home-rolled? Getting consistency and reliability right with something home-rolled is challenging.

Notes:

- Would love to see it in an S3-backed mode, either entirely diskless like WarpStream or as tiered storage.

- Love the simplified API. If possible, adding a Kafka compatible API interface is probably worth it to connect to the broader ecosystem.

Best of luck!
