Hi HN — I built Ayder because Kafka in 2025 feels like starting a car with a hand crank. # That's it. You're streaming. curl -X POST localhost:1109/broker/topics/orders/produce -d '{"item":"widget"}' Single binary. Zero dependencies. HTTP-native (not a proxy). Built in C with libuv. Performance (wrk2, real network, 3-node Raft, sync-majority writes):
Recovery time — the number nobody talks about:
Tested repeatedly. Zero data loss. Follower replays AOF, asks leader for missing offsets, catches up automatically. No manual intervention.What you get: - Append-only log with consumer groups + committed offsets - Raft consensus (3/5/7 nodes) with mTLS - KV store with CAS + TTL - Stream processing: filter, group_by, windowed joins (including cross-format Avro+Proto) - Idempotent produce, retention policies, Prometheus metrics I'm a solo founder from Kazakhstan, self-taught systems programmer. Spent 8 months building this. Looking for feedback on the API, what's missing, and early design partners. |
