  • kmq

    Kafka-based message queue

    • Project mention: FedNow Is Live | news.ycombinator.com | 2023-07-22

    thanks for the reply!

    I'm aware that Kafka is low-level (and that there is kmq, which tries to implement a message queue on top of it https://github.com/softwaremill/kmq/ ), but the exactly-once semantics seems isomorphic to having the sender and the receiver doing a 2 phase commit using the log.

    what are MQ's guarantees? how are they implemented?
