High-performance ORM layer for WordPress/WooCommerce with Shadow Tables

ShadowORM dramatically accelerates meta queries by storing post metadata in optimized "shadow tables" with native JSON support (MySQL 8.0+) or lookup tables (MySQL 5.7/MariaDB).

Features

  • Dual-Driver Strategy - Automatic detection of MySQL version
    • MySQL 8.0+: Native JSON columns with Multi-Valued Indexes
    • MySQL 5.7/MariaDB: Lookup tables with standard JOINs
  • Zero Configuration - Works out of the box after activation
  • WP-CLI Support - Full command-line interface for migrations
  • Admin Panel - Visual management of shadow tables
  • Transparent Integration - Intercepts get_post_meta() automatically
  • RAM Cache - In-memory caching for repeat reads

Requirements

  • PHP 8.1+
  • WordPress 6.0+
  • MySQL 5.7+ or MariaDB 10.2+

Installation

Via Composer

cd wp-content/plugins
git clone https://github.com/gotoweb/shadow-orm.git
cd shadow-orm
composer install

Manual

  1. Download the latest release from Releases
  2. Upload to wp-content/plugins/shadow-orm/
  3. Run composer install
  4. Activate in WordPress Admin

Quick Start

WP-CLI Commands

Command Description
wp shadow status Show migration status for all types
wp shadow migrate --type=<type> Migrate specific post type
wp shadow migrate --all Migrate all configured types
wp shadow migrate --dry-run Preview without changes
wp shadow rollback --type=<type> Remove shadow table
wp shadow benchmark --type=<type> Performance benchmark

How It Works

  1. Activation: Plugin installs db.php drop-in and MU-plugin loader
  2. Migration: wp shadow migrate copies meta to shadow tables
  3. Read Interception: get_post_meta() reads from shadow tables first
  4. Write Sync: save_post hook keeps shadow tables updated
  5. Query Optimization: meta_query uses JSON functions or lookup JOINs

Performance

Scenario Without ShadowORM With ShadowORM
Single meta read ~2ms <0.5ms
50 products with filters ~200ms ~50ms
Category page TTFB ~400ms ~150ms

Results on VPS with 2 vCPU, 4GB RAM, MySQL 8.0
