qpool 0.5.14

Trait based multiprocessing with queues

QPool

Description

Multiprocessing with Process Pools implemented using Processes and Shared Memory objects.

• Built in progress bar.
• Traits for rate-limiting, exponential backoff and retry, logging, and more.
• Graceful shutdown by default (CTRL+C 2x, will kill immediately).- Allows re-use of pool after join, cutting down on process spawning time.

Debugging Tips

• If hanging, investigate stop_workers, specifically the point of joining the processes, unclosed queues and resources can prevent process closure.

Progress Icons

• 📥 initial: Tasks submitted directly by the user. • 🌱 generated: Tasks produced by other tasks. • 📜 logs: Internal tasks created for logging messages. • ❌ failures: Tasks that failed after all retries were exhausted. • 🔃 retries: Tasks that failed and were scheduled for a retry. • ↪ skipped: Tasks that were skipped (e.g., by the debounce trait). • 🛑 cancelled: Tasks that were cancelled (e.g., by the timeout trait). • ⌛ expired: Tasks that expired before they could be executed.
