Solid Queue Coder
Overview
Solid Queue is Rails 8's default job backend—a database-backed Active Job adapter that eliminates the need for Redis. Jobs are stored in your database with ACID guarantees.
Configuration
Database Setup
yaml
# config/database.yml
production:
primary:
<<: *default
url: <%= ENV["DATABASE_URL"] %>
queue:
<<: *default
url: <%= ENV["QUEUE_DATABASE_URL"] %>
migrations_paths: db/queue_migrateQueue Configuration
yaml
# config/solid_queue.yml
production:
dispatchers:
- polling_interval: 1
batch_size: 500
workers:
- queues: [critical, default]
threads: 5
processes: 2
polling_interval: 0.1
- queues: [low_priority]
threads: 2
processes: 1
polling_interval: 1Application Configuration
ruby
# config/application.rb
config.active_job.queue_adapter = :solid_queue
# config/environments/production.rb
config.solid_queue.connects_to = { database: { writing: :queue } }Queue Design
Priority Strategy
ruby
class CriticalNotificationJob < ApplicationJob
queue_as :critical
queue_with_priority 1 # Lower = higher priority
end
class ReportGenerationJob < ApplicationJob
queue_as :low_priority
queue_with_priority 50
endConcurrency Control
ruby
class ProcessUserDataJob < ApplicationJob
limits_concurrency key: ->(user_id) { user_id }
end
class SyncContactJob < ApplicationJob
limits_concurrency key: ->(contact) { contact.id },
duration: 15.minutes,
group: "ContactOperations"
endRecurring Jobs
yaml
# config/solid_queue.yml
recurring:
cleanup_old_records:
class: CleanupJob
schedule: every day at 3am
queue: low_priority
sync_external_data:
class: SyncExternalDataJob
schedule: every 15 minutes
queue: defaultDeployment
Procfile
yaml
web: bundle exec puma -C config/puma.rb
worker: bundle exec rake solid_queue:startDocker Compose
yaml
services:
web:
command: bundle exec puma -C config/puma.rb
worker:
command: bundle exec rake solid_queue:startError Handling
ruby
class ExternalApiJob < ApplicationJob
retry_on Net::OpenTimeout, wait: :polynomially_longer, attempts: 5
discard_on ActiveJob::DeserializationError
rescue_from StandardError do |exception|
if executions >= 5
FailedJob.create!(job_class: self.class.name, error_message: exception.message)
else
raise exception
end
end
endDatabase Maintenance
ruby
namespace :queue do
task vacuum: :environment do
ActiveRecord::Base.connected_to(database: :queue) do
%w[solid_queue_ready_executions solid_queue_claimed_executions].each do |table|
ActiveRecord::Base.connection.execute("VACUUM ANALYZE #{table}")
end
end
end
endSolid Queue vs Sidekiq
| Feature | Solid Queue | Sidekiq |
|---|---|---|
| Infrastructure | Database only | Requires Redis |
| ACID guarantees | Yes | No |
| Transactional enqueue | Yes | No |
| Concurrency control | Built-in | Requires sidekiq-unique-jobs |
Anti-Patterns
| Anti-Pattern | Problem | Solution |
|---|---|---|
Wildcard queue * in prod | Unpredictable priority | Specify queue order |
| Single database | Contention with app | Separate queue database |
| Too many threads | Database exhaustion | Match pool size |
Output Format
When configuring Solid Queue, provide:
- Database Setup - Multi-database configuration
- Queue Config - solid_queue.yml settings
- Worker Setup - Procfile/Docker configuration
- Jobs - Example job classes with error handling
