Introduction

Ruby on Rails is known for making web development simple, fast, and efficient. This is why many businesses rely on professional Rails development services to build scalable applications.

With Rails 7.1+, Rails introduced a powerful new feature set called the Solid Suite, which includes Solid Queue, Solid Cache, and Solid Cable.

These tools help developers manage background tasks, improve application performance, and build real-time features using only a database. This means you no longer need additional tools like Redis or Memcached in many cases.

In this guide, we’ll explain what the Solid Suite is, how it works, its benefits, real-world use cases, and when you should use it.

What Is the Solid Suite in Rails?

The Solid Suite is a set of built-in tools in Rails that simplify how applications handle background jobs, caching, and real-time updates.

Traditional Rails Setup (Before the Solid Suite)

Traditionally, Rails applications use:

• Redis → for background jobs and real-time features
• Memcached or Redis → for caching
• Sidekiq → for job processing

While these tools are powerful, they increase system complexity and infrastructure costs—especially for teams focused on long-term Rails performance optimization.

With the Solid Suite

The Solid Suite replaces many of these tools by using your existing database (PostgreSQL or MySQL):

• Fewer tools to manage
• Lower infrastructure costs
• Easier setup and maintenance

Key Benefits of the Solid Suite

• No external services required
• Faster setup and deployment
• Lower operational costs
• Built directly into Rails
• Ideal for small-to-medium applications and teams offering Rails development services

1. Solid Queue: Background Jobs Made Simple

What Is Solid Queue?

Solid Queue is a built-in system for running background tasks in Rails. Instead of using Redis, it stores job data directly in your database, making Solid Queue in Rails a practical choice for simpler job processing.

Examples of Background Tasks

• Sending emails
• Generating reports
• Processing files
• Running scheduled tasks

Key Features

• Seamless integration with Active Job
• Supports PostgreSQL and MySQL
• Multi-threaded processing
• Job monitoring dashboard
• Easy installation

Installation

bin/rails solid_queue: install

class ReportGeneratorJob < ApplicationJob
  queue_as :default

  def perform(report_id)
    Report.find(report_id).generate!
  end
end

Best Use Cases

Solid Queue is ideal for:

• SaaS applications
• Internal tools
• Moderate workloads
• Applications that don’t use Redis

For very large systems with heavy workloads, Sidekiq is still the better choice.

2. Solid Cache: Faster Apps Without Redis

What Is Solid Cache?

Solid Cache improves application performance by storing frequently accessed data in the database instead of Redis. This makes Solid Cache in Rails suitable for applications focused on cost control and consistent Rails performance optimization.

Key Features

• No external services required
• Supports expiration and namespacing
• Works with existing Rails caching methods
• Simple configuration

Configuration

config.cache_store = :solid_cache_store

Rails.cache.fetch("featured_products", expires_in: 15.minutes) do
  Product.where(featured: true).to_a
end

Best Use Cases

Solid Cache is ideal for:

• Small-to-medium applications
• Cost-efficient deployments
• Platforms where Redis is unavailable

Redis may still be faster for very high-traffic applications.

3. Solid Cable: Real-Time Features Without Redis

What Is Solid Cable?

Solid Cable enables real-time features like chat and notifications using the database instead of Redis. With Solid Cable in Rails, teams can deliver real-time updates with less infrastructure overhead.

Key Features

• Database-based messaging
• Works seamlessly with Action Cable
• Suitable for moderate real-time usage
• Easy setup

Installation

bin/rails solid_cable:install

class ChatChannel < ApplicationCable::Channel
  def subscribed
    stream_from "chat_#{params[:room_id]}"
  end
end

Best Use Cases

Solid Cable is ideal for:

• Live notifications
• Chat applications
• Real-time dashboards

For large-scale real-time systems, Redis-based solutions are still recommended.

When Should You Use the Solid Suite?

Use the Solid Suite if:

• You want a simpler system architecture
• You want to reduce dependency on Redis or Memcached
• You are building small-to-medium applications
• You want faster setup and lower operational costs

When Should You Avoid the Solid Suite?

The Solid Suite may not be the best choice if:

• Your application requires very high performance
• You need advanced job processing features
• Your app handles massive real-time traffic
• Scalability is your top priority

Solid Suite vs. Redis-Based Architecture (Simple Comparison)

Conclusion

The Solid Suite in Rails 7.1+ represents a major step toward simpler and more efficient Rails applications. By using a single database for background jobs, caching, and real-time features, Rails significantly reduces system complexity and infrastructure costs.

While the Solid Suite does not completely replace Redis or Sidekiq, it provides a powerful alternative for many real-world applications supported by modern Rails development services. If you value simplicity, lower costs, and seamless Rails integration, the Solid Suite is definitely worth exploring.
