⚡ Lightning Talk: Navigating the Complexities of Stateful Workloads in Kubernetes
Lightningat Data on Kubernetes Day Europe 2025 · on Tuesday, 2025-04-01· at 12:15· Level 1 | Hall Entrance N10 | Room E·
summary
Runs through why local volumes fail for Postgres MongoDB Cassandra and argues for Software-Defined Storage via CSI with a concrete deployment: a six‑node cluster with a three‑node management plane pooling disks, support for block file and object access, and RWX for distributed apps. Covers strictly consistent replication, snapshots/clones plus remote backup for disaster recovery, QoS and data balancing, and calls out performance tax estimates like 30–45% vs near‑bare‑metal as a decision factor.
