Does Medusa work with a dockerized Cassandra?
Yes, Medusa works with Cassandra on Docker. In fact we have an out-of-the-box solution for it -- K8ssandra.
K8ssandra is a ready-made platform for running Apache Cassandra in Kubernetes using the DataStax Cassandra Operator (cass-operator) under the hood but with all the tooling built-in:
- Reaper for automated repairs
- Medusa for backups and restores
- Metrics Collector for monitoring with Prometheus + Grafana
- Traefik templates for k8s cluster ingress
To your question on "communication", Cassandra snapshots are not a database operation so it doesn't have anything to do with the driver. Snapshots are in fact done at the filesystem level using the Java IO FileUtils API to create hardlinks to the same inodes as data files on disk. Cheers!
