Iggy, S2, and OpenData Log Redefine Streaming Logs, Dropping Kafka Compatibility
New streaming log platforms—Apache Iggy, S2, and OpenData Log—ditch Kafka compatibility to chase higher performance, bottomless retention, and key‑based routing. Iggy uses Rust, TCP/QUIC/HTTP for ultra‑low latency, S2 stores data in object storage for endless history, while OpenData Log replaces partitions with routing keys. Their design choices could reshape how engineers build real‑time pipelines.
