Iggy

Iggy, a persistent message streaming platform written in Rust, is a relatively new project with impressive features. It already supports multiple streams, topics and partitions, at-most-once delivery, message expiry and TLS support over QUIC, TCP and HTTP protocols. Running as a single server, Iggy currently achieves high throughput for both read and write operations. With upcoming clustering and io_uring support, Iggy can be a potential alternative to Kafka.
