# Database Partition Manager

## Overview

Implement and manage table partitioning for PostgreSQL and MySQL to improve query performance and simplify data lifecycle management on large tables. This skill covers range partitioning (by date or ID), list partitioning (by category or region), hash partitioning (for even distribution), and composite partitioning.

## Prerequisites

- PostgreSQL 10+ (declarative partitioning) or MySQL 5.7+ (native partitioning)
- Database admin credentials with CREATE TABLE and ALTER TABLE permissions
- `psql` or `mysql` CLI for executing partition DDL
- Table size metrics: `SELECT pg_size_pretty(pg_total_relation_size('table_name'))` or `SELECT data_length FROM information_schema.TABLES`
- Query patterns on the target table (especially WHERE clause columns used for filtering)
- Maintenance window availability for initial partition migration on existing tables
