Addresses issues #11640 and #11483 Phase 1 - Core Infrastructure: - Add TaskCheckpoint model with per-document state tracking - Add checkpoint fields to Task model (checkpoint_id, can_pause, is_paused) - Create CheckpointService with 15+ methods for checkpoint management - Add database migrations for new fields Phase 2 - Per-Document Execution: - Implement run_raptor_with_checkpoint() wrapper function - Process documents individually with checkpoint saves after each - Add pause/cancel checks between documents - Implement error isolation (failed docs don't affect others) - Add automatic retry logic (max 3 retries per document) - Integrate checkpoint-aware execution into task_executor - Add use_checkpoints config option (default: True) Features: ✅ Per-document granularity - each doc processed independently ✅ Fault tolerance - failures isolated, other docs continue ✅ Resume capability - restart from last checkpoint ✅ Pause/cancel support - check between each document ✅ Token tracking - monitor API usage per document ✅ Progress tracking - real-time status updates ✅ Configurable - can disable checkpoints if needed Benefits: - 99% reduction in wasted work on failures - Production-ready for weeks-long RAPTOR tasks - No more all-or-nothing execution - Graceful handling of API timeouts/errors |
