Oxia - A Horizontally Scalable Alternative to Apache Zookeeper
summary
Oxia is presented as an Apache 2.0 licensed replacement for ZooKeeper using gRPC clients, a Kubernetes operator, shardable storage pods, a write ahead log plus LSM key value store, and push‑based replica replication instead of consensus, claiming a single shard node sustains about 100k TPS per shard node, sustained P99 <300ms latencies, and practical metadata scale jumping from millions to 10M topics out of the box with roadmap toward 100M.
