Data Structures

Overview

Use this skill to choose data structures with explicit tradeoffs, then justify the choice with workload assumptions and failure modes.

Scope Boundaries

• Use this skill when the task matches the trigger condition described in description.
• Do not use this skill when the primary task falls outside this skill's domain.

Inputs To Gather

• Required operations (lookup, insert, delete, scan, range, top-k).
• Read/write ratio and mutation frequency.
• Data volume now and forecast at peak.
• Latency/memory constraints and concurrency model.
