PipelineFlowEngine 1.0.0

This repository provides a robust and extensible implementation of a unidirectional processing pipeline flow designed to execute a series of interdependent methods. The pipeline architecture implementation is based on the step-by-step execution model, where each step represents a distinct unit of logic that contributes to the overall workflow.

Key Features

• Ordered Execution: Steps are executed sequentially in a single direction, preserving a clear and predictable execution flow.

• Step Enablement Control: Each step can be individually enabled or disabled based on runtime conditions or configuration, allowing for dynamic pipeline customization.

• Custom Execution Order: Although the default flow is linear, the execution order can be explicitly configured to suit specific business logic or integration scenarios.

• Pre-Execution Validation: Before a step is executed, it can optionally perform validation to ensure all preconditions are met. If validation fails, the pipeline can halt, skip or retry the step based on configuration.

• Retry Policies: Built-in support for retry mechanisms allows transient failures to be handled gracefully, with options for retry count, delay strategies, and exception filtering.

• Execution Logging: Each step's execution details—including status, duration, and any exceptions—are logged to facilitate debugging, monitoring, and auditability.

• Pipeline failure strategy: After defining the pipeline, you have the ability to specify how the system should respond to step failures, including strategies such as skipping the step, halting execution, or triggering retries.

This pattern is especially useful for workflows that involve multiple conditional processing steps, such as:

• Data transformation and enrichment pipelines;
• Business rule evaluations;
• Integration workflows with external services;
• Validation and preprocessing chains.

The pipeline is designed with extensibility in mind. Developers can:

• Define new steps by implementing a common interface or base class;
• Inject dependencies into steps using constructor injection;
• Plug in custom validation or retry strategies;
• Persist or export execution logs as needed.
