Four open source Kubernetes PVC backends compared: Ceph RBD, OpenEBS Local PV ZFS, Mayastor and DRBD with LINSTOR. Whether the application already replicates decides the choice; Ceph RBD brings snapshots and backups, but its multi-site mirroring is not production-ready, unlike Ceph RGW multi-site.
As someone who’s spent years optimizing data storage performance, I’m genuinely impressed by TigerBeetle’s bold architectural choices: https://lnkd.in/eS3bfHHQ 🎯 Single-core design for maximum throughputInstead of fighting contention with complex locking, they funnel all writes through one optimized core. For high-contention Read more
MinIO has just announced that the open source project is now in maintenance-only mode: no new features, no regular PR review, only best-effort community support.If your data lake, AI workloads or internal S3-compatible storage rely on MinIO, this is no Read more
Update, September 2026: the sibling failure hit site replication. ILM expiration on a replicated mesh created delete markers that MinIO re-probes forever: 706 million replication requests in 48 hours, 96.8 percent answered 405, no data moved. Full write-up: how 684 Read more
