2025-09-18
Facing exploding data storage needs, algorithmic trading firm XTX built TernFS, a distributed filesystem scaling to tens of exabytes and millions of concurrent clients. TernFS employs sharded metadata storage, a decentralized design, and supports multi-region deployment, achieving high availability and performance. Key features include immutable files, redundant data storage, fault tolerance, and flexible storage policies. TernFS is already used extensively at XTX and is open-sourced for community use, offering a novel solution for large-scale data storage.
