Q

Q is a simple yet robust persistent message/task queue implemented in Go.

Features

• Message Confirmation & Retry: Messages remain in queue until explicitly confirmed by consumers
• Message Persistence: Reliable storage of messages to prevent data loss
• Priority Queue: Support for message prioritization to handle urgent tasks first
• Simple API: Easy to integrate and use
• High Performance: Optimized for speed and efficiency
• Zero Dependencies: Standalone implementation with no external requirements

Safety Guarantees

Messages in Q are handled with strong safety guarantees:

• Messages persist until explicitly confirmed by consumers
• Unconfirmed messages are automatically recycled back to the queue
• No message loss even in case of crashes or failures
• Priority levels are preserved during message recycling and recovery
