omniTask 1.1.0

A powerful Python-based workflow automation tool

OmniTask

A powerful, pure Python workflow automation engine designed for simplicity and scalability.

Overview

OmniTask is a modern workflow automation engine that allows you to build complex data processing pipelines with ease. It provides a clean API for defining tasks, managing dependencies, and executing workflows with features like streaming, caching, and parallel execution.

Key Features

• Pure Python: Built entirely in Python with no external dependencies beyond PyYAML
• Async/Await Support: Full asynchronous execution for maximum performance
• Streaming Tasks: Real-time data processing with streaming capabilities
• Intelligent Caching: Memory, file-based, and Redis distributed caching for optimized performance
• Dependency Management: Automatic dependency resolution and execution ordering
• Task Groups: Parallel execution with configurable concurrency limits
• Conditional Execution: Execute tasks based on conditions and previous results
• Progress Tracking: Built-in progress monitoring and callbacks
• Error Handling: Comprehensive error handling with retry mechanisms
• Workflow Validation: Static analysis and validation of workflow definitions
• YAML Configuration: Define workflows using simple YAML files

Installation

pip install omniTask

Quick Start

Creating a Simple Workflow

from omniTask import Workflow, Task, TaskResult

class DataProcessorTask(Task):
    task_name = "data_processor"
    
    async def execute(self):
        data = self.config.get('data', [])
        result = sum(data)
        return TaskResult(success=True, output={"sum": result})

async def main():
    # Create workflow
    workflow = Workflow("example")
    workflow.registry.register(DataProcessorTask)

    # Add task
    task = workflow.create_task("data_processor", "process", {"data": [1, 2, 3, 4, 5]})

    # Execute
    results = await workflow.run()
    print(results["process"].output)  # {"sum": 15}

if __name__ == "__main__":
    import asyncio
    asyncio.run(main())

Using YAML Configuration

name: data_pipeline
tasks:
  load_data:
    type: file_reader
    config:
      file_path: "data.csv"
  
  process_data:
    type: data_processor
    config:
      operation: "aggregate"
  
  save_results:
    type: file_writer
    config:
      file_path: "results.json"

dependencies:
  process_data:
    - load_data
  save_results:
    - process_data

from omniTask import WorkflowTemplate

template = WorkflowTemplate("workflow.yaml")
workflow = template.create_workflow()
results = await workflow.run()

Why OmniTask?

Simple Yet Powerful

• Minimal Learning Curve: Start with basic tasks and grow into complex workflows
• Intuitive API: Clean, Pythonic interface that feels natural
• Flexible Configuration: Support for both code and YAML-based workflow definitions

Built for Scale

• Async-First Design: Handle thousands of concurrent tasks efficiently
• Smart Caching: Avoid redundant computations with intelligent caching
• Streaming Support: Process data in real-time as it becomes available

Production Ready

• Comprehensive Testing: Extensive test coverage and validation
• Error Resilience: Built-in retry mechanisms and error handling
• Monitoring: Progress tracking and detailed logging
• Validation: Static analysis of workflow definitions

Architecture

OmniTask follows a clean, modular architecture:

• Core Engine: Task execution, dependency resolution, and workflow management
• Task System: Extensible task framework with streaming support
• Caching Layer: Pluggable caching system for performance optimization
• Validation System: Static analysis and runtime validation
• Utility Layer: Logging, path parsing, and helper functions
