OpenData Log is an MIT-licensed Rust service that stores ordered logs directly on object storage with per-key indexing. It handles millions of individual logs efficiently by using a segmented LSM tree keyed by (key, sequence), which cuts read amplification compared to Kafka. Readers can scale by key-range without repartitioning or data reshuffling.
