Common Cassandra Anti-Patterns
- Huge partitions that grow without bounds
- Heavy use of unsupported ad hoc filters
- Excessive tombstones from poor delete or TTL design
- Using batches as a bulk-ingestion shortcut
- Ignoring repairs, compaction, and storage overhead
Performance Tuning Mindset
Performance tuning in Cassandra is deeply connected to data modeling. The best optimization often comes from better partition keys, more appropriate bucketing, safer table design, and more realistic consistency settings rather than only parameter tuning.
Production Best Practices
Advanced teams keep clusters healthy through observability, careful schema evolution, capacity planning, repair discipline, tested failover procedures, and workload-aware tuning. Cassandra success comes from operational maturity as much as from query syntax knowledge.
Why Simplicity Helps
The most stable Cassandra systems often use simpler access patterns, predictable partitioning, and clear service boundaries. Complexity is possible, but it should be introduced carefully and only when the workload truly needs it.
