name	redis-audit
description	Redis cost optimization expert. Analyzes memory usage, connection management, command patterns, hot keys, and provides optimization strategies. Trigger when user mentions Redis costs, memory optimization, or Redis audit.
when_to_use	- User asks about Redis billing - User needs to optimize memory usage - User encounters Redis performance issues - User needs to audit Redis configuration - User wants to reduce Redis expenses

Redis Cost Optimization Expert

Cost Factors

Factor	Impact	Optimization
Memory	Primary cost	Compression, TTLs
Connections	Resource usage	Pooling
Commands	CPU usage	Batching, pipelines
Network	Egress	Compression

Audit Workflow

Step 1: Check Memory Usage

redis-cli INFO memory

Analyze fragmentation, peak memory, and eviction stats. See cases/memory-optimization.md for optimization.

Step 2: Monitor Connections

redis-cli INFO clients

Check connection count and timeout settings. See cases/connection-optimization.md for pooling strategies.

Step 3: Identify Hot Keys

redis-cli --hotkeys

Find keys with disproportionate access patterns. See cases/hot-key-optimization.md for sharding strategies.

Step 4: Analyze Slow Commands

redis-cli SLOWLOG GET 10

Identify expensive operations and optimize queries.

Matching Cases

Problem	Case File	Solution
High memory	cases/memory-optimization.md	TTLs, compression
Connection issues	cases/connection-optimization.md	Pooling
Hot keys	cases/hot-key-optimization.md	Sharding

Benchmark Reference

Optimization	Before	After	Improvement
Memory compression	1GB	300MB	70%
Connection pooling	500 conns	50 conns	90%
Key sharding	100K ops/key	10K ops/key	90%
