RBD mirroring in production is one of the patterns I audit and design: Ceph storage consulting. Alpha Feature in Production… Good Idea? The most promising approach, journal-based mirroring, offers near real-time replication and faster failover. However, it’s currently an alpha feature in the Ceph CSI driver and relies on rbd-nbd, Read more
Choosing a PVC backend is an architecture decision I review; the Ceph storage consulting page describes the cluster side. Most discussions about PVC focus on on-prem deployments, but many of these technologies are equally relevant in the cloud, especially when using managed block storage like AWS EBS, which caps at Read more
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 financial workloads (think central bank switches processing millions of transactions), 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 longer a theoretical risk – it’s an operational one. Over 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 million HTTP 405s exposed the delete-marker replication loop. Introduction In Read more
Thanos is a widely adopted open-source project that extends Prometheus’ capabilities, offering long-term storage, global querying, and downsampling. It’s a powerful tool for monitoring and observability, but like any complex system, it has its quirks. Thanos is cloud native and use s3 as its main storage backend. It can have Read more
