Learn how to enable Redis Object Caching for improved WordPress performance on Unity Pro plans.

What is Redis Object Caching?

Redis Object Caching stores frequently-accessed database queries in memory, reducing database load and improving response times for dynamic content that can't be page cached.

While our Smart Cache feature handles full page caching, Redis improves performance for:

  • Admin dashboards

  • User-specific content

  • WooCommerce checkout processes

  • Complex database queries

  • Plugin operations that bypass page cache

Which Plans Include Redis?

Redis Object Caching is available on Unity Pro plans only at no additional cost.

Available on:

  • Unity Pro Small

  • Unity Pro Medium

  • Unity Pro Large

  • Unity Pro Custom

Not available on Unity or Infinity plans.

How to Enable Redis Object Caching

  1. Log in to my.wordify.com

  2. Navigate to Configure Site > Hosting > Redis

  3. Click Enable

  4. Done

The process takes a few moments to complete. Once enabled:

  • A dedicated Redis instance is provisioned for your site

  • The Redis plugin is automatically installed in WordPress

  • Connection settings are configured automatically

  • No credentials or configuration files needed

How It Works

Each Unity Pro site receives its own isolated Redis 8.x instance with memory allocation optimized for your plan size.

When WordPress needs data:

  1. It checks Redis first for cached query results

  2. If found in Redis (cache hit), data is returned in microseconds

  3. If not found (cache miss), WordPress queries the database and stores the result in Redis

  4. Subsequent requests for the same data are served from Redis

The Redis plugin handles all communication between WordPress and Redis, with automatic fail-over to standard database queries if Redis becomes unavailable.

Technical Details

  • Redis Version: 8.x

  • Architecture: Isolated instance per site

  • Failover: Automatic fallback to database queries

How to Disable Redis

To disable Redis Object Caching:

  1. Log in to my.wordify.com

  2. Navigate to Configure Site > Hosting > Redis

  3. Click Disable

Your site will immediately revert to standard database queries. The Redis instance and plugin will be removed.
