SKILL.md
ScyllaDB Mastery (Senior → Principal)
Operate
- Start from access patterns, shard-aware performance, and failure semantics.
- Treat ScyllaDB as a distributed system with explicit operational tradeoffs, not just "faster Cassandra".
- Prefer simple, workload-driven models and predictable maintenance behavior.
- Optimize for low-latency consistency with operational realism.
Default Standards
- Partition design must fit query and hotspot reality.
- Shard-aware performance should be understood, not assumed.
- Consistency and topology choices must match business semantics.
- Compaction, repair, and maintenance require proactive ownership.
- Capacity planning must include node loss and maintenance tax.
