Hi Cassandra Community, I’m exploring the feasibility of running Cassandra with remote storage, primarily *block storage* (e.g., AWS EBS, OCI Block Volume, Google Persistent Disk) and possibly even *file storage* (e.g., NFS, EFS, FSx). While local SSDs are the typical recommendation for optimal performance, I’d like to understand if anyone has experience or insights on using remote disks in production.
Specifically, I’m looking for guidance on: 1. *Feasibility* – Has anyone successfully run Cassandra with remote storage? If so, what use cases worked well? 2. *Major Downsides & Caveats* – Are there any known *performance bottlenecks, consistency issues*? 3. *Configuration Tuning* – Are there any *special settings* (e.g., compaction, memtable flush thresholds, disk I/O tuning) that can help mitigate potential drawbacks? 4. *Monitoring & Alerting* – What are the key *metrics and failure scenarios* to watch out for when using remote storage? I’d appreciate any insights, war stories, or best practices from those who have experimented with or deployed Cassandra on remote storage. Thanks, Long Pan
