Cassandra Performance Tuning

- Analyze and optimize read/write performance and latency.

- Tune compaction, caching, consistency levels, tombstones, SSTables, and Cassandra configuration.

- Identify hot partitions, slow queries, and resource bottlenecks.

Node Expansion &

- Cluster Management

- Add, replace, remove, and decommission Cassandra nodes safely.

- Perform cluster expansion and capacity upgrades with minimal production impact.

- Manage token distribution, bootstrap/streaming, repair, cleanup, and cluster rebalancing.

Backup &

- Recovery

- Implement and maintain Cassandra backup and restore strategies.

- Perform snapshots, incremental backups, and point-in-time recovery where supported by the backup solution.

- Conduct recovery testing and support disaster-recovery procedures.

JVM &

- System Tuning





- Tune Cassandra JVM heap, garbage collection, and memory settings.

- Troubleshoot GC pauses, heap pressure, CPU, disk I/O, and memory issues.

- Tune Linux/OS and storage configurations for Cassandra workloads.

Monitoring &

- Troubleshooting

- Monitor cluster health, availability, latency, throughput, disk usage, compactions, dropped messages, GC, and repairs.

- Troubleshoot production issues including node failures, high latency, timeouts, replica inconsistencies, and capacity problems.

- Solid experience with nodetool, Cassandra logs, metrics, tracing, and monitoring/alerting platforms.
