Redis Pub Sub

redis pub sub — production database configuration, optimization, and operations for redis.

Redis Pub Sub

Run redis in production with confidence — from schema design to disaster recovery.

Overview

This skill covers redis pub sub for applications that need reliable, performant data storage. It handles the full lifecycle from initial setup through scaling, optimization, and operational management.

Database issues are among the most costly problems in production systems — slow queries cause user-facing latency, data loss destroys trust, and scaling bottlenecks limit growth. This skill addresses all three with proven patterns from high-traffic production systems.

The skill produces configurations, queries, and operational procedures that have been battle-tested at scale. It emphasizes data integrity, query performance, and operational simplicity.

When to Use

Activate this skill when the user needs to:

Set up a new redis instance or cluster

Optimize slow database queries or operations

Design schemas for new features or applications

Configure replication, backups, or disaster recovery

Migrate data between databases or versions

Debug production database performance issues

Core Capabilities

Schema Design

Creates normalized, efficient database schemas with proper indexing strategies, constraint definitions, and migration scripts. Balances normalization with query performance.

Query Optimization

Analyzes and rewrites slow queries using EXPLAIN plans, index recommendations, and query restructuring. Identifies N+1 problems, missing indexes, and suboptimal join patterns.

Operations & Monitoring

Configures monitoring dashboards, alerting thresholds, and automated health checks. Sets up backup schedules, retention policies, and recovery procedures.

Scaling Strategies

Implements read replicas, connection pooling, sharding strategies, and caching layers. Provides capacity planning guidance based on growth projections.

Example Prompts

Users might ask:

"Design a schema for the e-commerce product catalog"

"Optimize the slow queries in the analytics dashboard"

"Set up redis replication with automatic failover"

"Create a migration script to add the new user preferences table"

"Configure redis backup and point-in-time recovery"

Best Practices

Always use migrations — Never modify production schemas manually — use versioned migration scripts that can be reviewed and rolled back

Index based on query patterns — Create indexes that match your actual query WHERE/ORDER BY/JOIN patterns, not arbitrary columns

Monitor connection usage — Connection exhaustion is a common cause of production outages — monitor and alert on pool usage

Test with production-like data — Performance characteristics change dramatically with data volume — always test with realistic dataset sizes

Plan for failure — Assume every component will fail — implement backups, replicas, and automated recovery

Common Pitfalls

⚠️ Adding indexes without analyzing query patterns — unused indexes waste storage and slow writes

⚠️ Not setting query timeouts — a single runaway query can take down the entire database

⚠️ Ignoring connection pool limits — leads to connection exhaustion under load

⚠️ Testing with small datasets — queries that are fast with 100 rows may be catastrophically slow with 10 million

Output Format

Generates SQL scripts, configuration files, migration files, and operational runbooks. Includes inline comments explaining design decisions and performance implications.

Prerequisites

redis server installed or cloud instance provisioned
