Automatically recover running tasks with stale heartbeats on worker startup, preventing tasks from being permanently stuck after container restarts. Key changes: - Add HEARTBEAT_TIMEOUT_SECONDS constant (default 300s, configurable via env) - Add _recover_stale_running_tasks() function: * Scans for status='running' tasks with heartbeat timeout * No progress (processed=0) → reset to pending (auto-retry) * Has progress (processed>0) → mark as failed with Chinese error message * Each task recovery is independent (single failure doesn't affect others) * Skip recovery if timeout is 0 or negative (disable feature) - Call recovery function in _worker_loop() before polling loop - Update file header comments to reflect recovery mechanism Recovery logic: - Query: status='running' AND (heartbeat_at IS NULL OR heartbeat_at < NOW() - timeout) - Decision based on processed_images count - Clear run_token to allow other workers to claim - Single transaction per task for atomicity Edge cases handled: - Database unavailable: recovery failure doesn't block worker startup - Concurrent recovery: UPDATE WHERE status='running' prevents duplicates - NULL heartbeat: extreme case (crash right after claim) also recovered - stop_requested tasks: automatically excluded by _fetch_pending_task() Testing: - 8 unit tests all passed: * No timeout tasks * Timeout disabled * No progress → pending * Has progress → failed * NULL heartbeat recovery * Multiple tasks mixed processing * DB error doesn't crash * Negative timeout disables feature

If you like this project, please give it a Star⭐️!
🌟 Core Features
- Core Modules: Data Collection, Data Management, Operator Marketplace, Data Cleaning, Data Synthesis, Data Annotation, Data Evaluation, Knowledge Generation.
- Visual Orchestration: Drag-and-drop data processing workflow design.
- Operator Ecosystem: Rich built-in operators and support for custom operators.
🚀 Quick Start
Prerequisites
- Git (for pulling source code)
- Make (for building and installing)
- Docker (for building images and deploying services)
- Docker-Compose (for service deployment - Docker method)
- Kubernetes (for service deployment - k8s method)
- Helm (for service deployment - k8s method)
This project supports deployment via two methods: docker-compose and helm. After executing the command, please enter the corresponding number for the deployment method. The command echo is as follows:
Choose a deployment method:
1. Docker/Docker-Compose
2. Kubernetes/Helm
Enter choice:
Clone the Code
git clone git@github.com:ModelEngine-Group/DataMate.git
cd DataMate
Deploy the basic services
make install
If the machine you are using does not have make installed, please run the following command to deploy it:
# Windows
set REGISTRY=ghcr.io/modelengine-group/
docker compose -f ./deployment/docker/datamate/docker-compose.yml up -d
docker compose -f ./deployment/docker/milvus/docker-compose.yml up -d
# Linux/Mac
export REGISTRY=ghcr.io/modelengine-group/
docker compose -f ./deployment/docker/datamate/docker-compose.yml up -d
docker compose -f ./deployment/docker/milvus/docker-compose.yml up -d
Once the container is running, access http://localhost:30000 in a browser to view the front-end interface.
To list all available Make targets, flags and help text, run:
make help
Build and deploy Mineru Enhanced PDF Processing
make build-mineru
make install-mineru
Deploy the DeerFlow service
make install-deer-flow
Local Development and Deployment
After modifying the local code, please execute the following commands to build the image and deploy using the local image.
make build
make install dev=true
Uninstall
make uninstall
When running make uninstall, the installer will prompt once whether to delete volumes; that single choice is applied to all components. The uninstall order is: milvus -> label-studio -> datamate, which ensures the datamate network is removed cleanly after services that use it have stopped.
