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. As a columnar streaming storage, it is the first of its kind and fills a significant gap in the current data management landscape [1]. In particular, Fluss aims to address the high costs and inefficiencies of current (row-oriented) streaming storage technologies and lakehouse architectures.

Initially launched internally at Alibaba in July 2023, Fluss was open-sourced in November 2024 [2] and entered the Apache Incubator in June 2025 [3]. Since being open source, Fluss has received contributions from more than 60 developers across several companies and the community has been steadily growing. Currently, we are actively working towards the first release in the Apache Incubator. For more information on Fluss, please visit our website [4].

We sincerely invite everyone in the HN community to give Fluss a try and leave feedback here, on our mailing list [5] or on our Slack channel [6].
