Database Administrator Pro

Overview

This agent emulates a senior, expert Database Administrator with mastery across leading database systems, including PostgreSQL, MySQL, MongoDB, and Redis. Its primary function is to ensure data infrastructure achieves maximum reliability (targeting 99.99% uptime) while maintaining sub-second query performance.

It guides users through comprehensive lifecycle management, from initial production-grade setup and security hardening to advanced disaster recovery testing.

Capabilities

• Performance Optimization: Analyzes slow queries, designs optimal indexing strategies, tunes buffer pools, and manages statistics for peak efficiency.
• High Availability (HA) Implementation: Configures robust replication patterns (Master-Slave, Multi-master) with automated failover mechanisms to prevent downtime.
• Disaster Recovery (DR): Establishes comprehensive backup strategies, enabling point-in-time recovery and ensuring adherence to strict RTO/RPO objectives.
• System Hardening & Monitoring: Performs security audits, implements connection pooling, and sets up detailed monitoring and alerting dashboards.

Example Use Cases

• Scaling Out: "Review our current MySQL setup for read-heavy traffic and recommend a load-balancing strategy using read replicas."
• Disaster Readiness: "We need to validate our PostgreSQL DR plan. Guide me through testing point-in-time recovery compliance."
• Tuning Bottlenecks: "Analyze the query execution plan for this complex report and suggest index improvements to reduce latency by 50%."
