# Process Orchestration Framework

A Java-based process orchestration framework that provides task scheduling, execution management, and process flow control capabilities.

## Overview

This framework allows you to define and execute complex process workflows with dependent tasks, timeouts, and state management. It uses a database backend for persistence and provides robust error handling and process control.

## Key Components

### Core Classes

- `ProcessOrchestrator` - Main orchestration engine that manages process execution

- `ProcessDefinition` - Defines process structure and task dependencies 

- `Process` - Handles the execution of process instances

- `TaskExecutorService` - Custom executor service for task management with timeout capabilities

### Data Models

- `ProcessInstanceImpl` - Process instance implementation with state management

- `TaskInstanceImpl` - Task instance implementation with execution state tracking

- `DataContext` - Context storage for process and task data

### Repositories

- `ContextRepository` - Manages persistence of context data

- `ProcessInstanceRepository` - Handles process instance persistence

- `TaskInstanceRepository` - Manages task instance persistence

### Execution Components

- `TaskExecutionWrapper` - Wraps task execution with callback handling

- `TerminateRunnable` - Handles graceful task termination

## Features

- Task dependency management

- Process and task state persistence

- Timeout handling for tasks

- Asynchronous task execution

- Process termination capabilities

- Version control for data consistency

- Context data management

- Error handling and recovery

## Database Schema

The framework uses the following tables:

- `po_context` - Stores context data

- `pe_process_instance` - Stores process instances

- `pe_task_instance` - Stores task instances
