    Apache Fluss (Incubating) – Streaming Storage for Real-Time Analytics▲7

    Hey HN! On behalf of the Fluss community, I would like to share Apache Fluss (Incubating). Fluss is a next-generation streaming storage designed for real-time analytics.

Recently, I've implemented a higher level, asynchronous REST-API with Kotlin (Coroutines) and Vert.x in a seperate module. The system is…
