Wombat Task Queue

Wombat Task Queue, an open-source task queue service built with Go and leveraging MongoDB for storage, is engineered to simplify task management and processing in distributed applications. Supports prioritization.

Planned Features

• Task Prioritization: Assign priority levels to tasks for processing.
• Stale Task Handling: Automatically remove tasks that have been pending for too long.
• Task Metrics: Track task processing times and success rates.
• gRPC Support: Use gRPC for communication.

Usage

Installation

1. Clone the repository:

git clone https://github.com/xis/wombat.git

2. Navigate to the project directory:

cd wombat

3. Build the project:

go build -o wombat ./cmd

Usage

Setting Up Environment Variables

Wombat uses environment variables for configuration. Before starting the service, ensure you have set the following variables:

• MONGO_URI: The connection string to your MongoDB instance.
• HTTP_ADDR: The HTTP address and port the service will listen on (default: :8080).

Starting the Service

To start the Wombat service, run:

./wombat

API Endpoints

Wombat provides the following RESTful API endpoints for managing tasks within queues:

• GET /queues/:queueID/tasks: Retrieve pending tasks from a specific queue.
• POST /queues/:queueID/tasks?priority=8: Create a new task in a specific queue. The request body must be a JSON.
  • Here is an example of a request body:

    {
      "user_id": 8,
      "video-url-to-process": ".../australia.mp4"
    }

• PUT /queues/:queueID/tasks/:taskID: Update the status of a specific task.
  • Here is an example of a request body:

    {
      "status": "completed"
    }

Task Prioritization

When creating a new task, you can specify a priority level. The higher the number, the higher the priority. If no priority is specified, the task will default to priority level 0.

Development

For developing on Wombat, you will need a Go development environment set up and an accessible MongoDB instance for testing.
