Built for Real-World Scale
From startups to enterprises, BullMQ powers mission-critical workloads across every industry. See how message queues solve real problems.
E-Commerce Order Processing
Process orders asynchronously - validate inventory, charge payments, send confirmations, and trigger fulfillment. Handle Black Friday traffic without breaking a sweat.
- Job flows for multi-step checkout
- Retry failed payment attempts
- Rate limit shipping API calls
Video & Media Processing
Transcode videos, generate thumbnails, and process uploads in background workers. Scale processing power independently from your web servers.
- Long-running jobs with progress tracking
- Priority queues for premium users
- Automatic retries on transcoding failures
Email & Notification Campaigns
Send millions of emails without blocking your app. Schedule campaigns, throttle delivery to respect provider limits, and track delivery status.
- Rate limiting for ESP compliance
- Scheduled/delayed delivery
- Batch processing with concurrency control
Webhook Processing
Receive webhooks instantly, process them reliably. Never lose a Stripe payment notification or GitHub event again.
- Instant acknowledgment, async processing
- Deduplication prevents double-processing
- Dead letter queues for failed webhooks
Data Pipelines & ETL
Build reliable data pipelines that extract, transform, and load data across systems. Handle failures gracefully with automatic retries.
- Job dependencies for pipeline stages
- Scheduled data syncs
- Backpressure handling
AI/ML Job Orchestration
Queue inference requests, batch training jobs, and orchestrate GPU workloads. Handle bursty AI traffic without overloading expensive compute resources.
- Priority queues for real-time vs batch
- Resource-aware concurrency limits
- Long-running job support
Document Generation & Reports
Generate PDFs, invoices, and complex reports in the background. Users get instant response while heavy processing happens asynchronously.
- Progress events for UI updates
- Scheduled report generation
- Multi-step document workflows
IoT & Sensor Data
Ingest high-volume sensor data, process in batches, and trigger alerts. Handle millions of data points without overwhelming your database.
- Batch aggregation jobs
- Rate limiting for downstream services
- Real-time alerting pipelines
Why Use a Message Queue?
Message queues are the backbone of scalable, reliable applications. Here's why:
Decouple Components
Separate concerns between services. Your API responds instantly while workers handle the heavy lifting.
Increase Reliability
Automatic retries, dead letter queues, and persistent storage ensure no job is ever lost.
Scale Horizontally
Add more workers when load increases. Scale processing power independently from your web tier.
Handle Spikes
Queue absorbs traffic bursts. Process at your own pace without dropping requests.
Control Flow
Rate limit external API calls, prioritize important jobs, and manage resource consumption.
Schedule & Delay
Run jobs at specific times, implement cron-like schedules, or delay processing for later.
