Show HN: ZeroFS – A log-structured filesystem for S3
ZeroFS is a log-structured filesystem designed to serve S3-compatible storage as POSIX filesystems or block devices. It emphasizes data integrity and performance through rigorous CI testing, including Jepsen failover suites and kernel-level stress tests.
Why it matters
It provides a robust solution for bridging cloud-native object storage with traditional filesystem requirements, which is critical for modern infrastructure scalability.
ZeroFS serves S3-compatible buckets as POSIX filesystems over NFS and 9P, or as raw block devices over NBD. The engine is log-structured : writes go out as immutable objects and compaction reclaims what you delete. Data is compressed and encrypted before upload, and warm reads come from local cache in microseconds.
