ScyllaDB Summit Preview: Rebuilding the Ceph Distributed Storage Solution with Seastar

In an interview leading up to the ScyllaDB Summit 2018, Kefu Chai, a Software Engineer at Red Hat, discusses his presentation on rebuilding the Ceph distributed storage solution using the Seastar framework. Chai, who has an extensive background in developing kernel modules and middleware, explains how the need for higher throughput and lower latency in storage solutions led to adopting Seastar, known for its share-nothing model and zero locking tolerance. He highlights Ceph's appeal as an open-source, decentralized storage platform offering unified block, object, and filesystem access. Chai also notes the challenges of integrating Seastar into Ceph, a dynamic project not originally designed for Seastar's architecture, and mentions the ongoing process of rebuilding Ceph's infrastructure with Seastar. He plans to explore Seastar's impact on performance, emphasizing the importance of understanding threading models for attendees of his talk.
