APACHE KAFKA VS APACHE IGGY: SAME LOG, DIFFERENT ENGINE

Summary from the TLDR Data newsletter

Apache Iggy is a Rust streaming engine with Kafka-like logs and consumer groups, optimized around thread-per-core execution and modern Linux I/O. It looks promising for low-latency single-node or simpler deployments, but Kafka still has the deeper production story for replication, exactly-once semantics, compaction, and multi-region operations.
