Job Stream Processing for Monolithic Application Refactoring

The patent divides the monolithic application into discrete, reusable components called 'jobs' that can be independently developed, tested, and deployed. Each job is a self-contained unit with defined inputs and outputs, allowing modifications without affecting the entire system. This segmentation enables parallel development and reduces the time required for changes by isolating modifications to specific job modules rather than requiring system-wide retesting.

The patent creates a universal framework that supports multiple file formats and processing functions through a standardized job interface. Jobs can be designed to handle various input formats (fixed-width, variable-length, delimited) and output requirements without requiring framework changes. This universality allows a single job to serve multiple purposes or be reused across different processing scenarios, reducing the need for custom development for each requirement.

By segmenting the application into independent jobs with clear interfaces, the patent reduces modification complexity. Each job can be developed, tested, and modified independently without requiring understanding of the entire monolithic structure. The standardized job interface provides simple integration rules, transforming the complex modification process into a systematic assembly of discrete components.

The patent introduces a job manager as an intermediary layer between the processing framework and individual jobs. This mediator handles the complexity of job coordination, error handling, and resource management, allowing developers to focus solely on job logic without dealing with system-level complexity. The job manager abstracts away the infrastructure details, simplifying both development and modification processes.

Segmenting the application into independently testable jobs enables parallel development and testing. Each job can be unit-tested in isolation before integration, allowing comprehensive testing without sequential dependency. This segmentation maintains reliability through thorough testing while improving productivity by enabling concurrent development of multiple jobs or modifications.

The patent implements preliminary testing of individual jobs before integration into the full system. Each job is tested independently with predefined test cases that verify its functionality and error handling. This preliminary action ensures that jobs are robust before being assembled into the complete processing pipeline, maintaining overall system reliability while reducing the need for extensive retesting after integration.

The patent segments the application into independently deployable jobs that can be activated or deactivated without affecting other parts of the system. This allows selective deployment of modified jobs rather than requiring complete application re-deployment. The job manager handles the deployment coordination, enabling granular control over which jobs are active and when changes are applied to the running system.

The patent implements a dynamic deployment model where jobs can be added, modified, or removed from the active system without shutting down the entire application. The job manager dynamically loads and unloads jobs based on configuration changes, allowing the system to adapt to modifications in real-time or during maintenance windows. This dynamic approach maintains ease of operation while significantly reducing deployment time for changes.
