PROFILE
Mark Patton
Mark Patton contributed to the DSpace/DSpace repository by delivering three backend features and resolving a critical build issue over three months. He upgraded the S3 BitStore service to AWS SDK v2, introducing asynchronous operations and CRT client integration to improve storage throughput and reliability. Mark addressed a classpath collision by refining Maven dependency management, which stabilized builds and reduced resource loading errors. He also enhanced bitstream download handling, enabling inline viewing in browsers through precise content-disposition headers. His work demonstrated depth in Java, asynchronous programming, and backend development, aligning technical improvements with business goals for scalable, maintainable storage services.

Nov 1, 2025November 2025 focused on delivering the S3 Bitstore Service AWS SDK v2 integration in DSpace/DSpace, enabling asynchronous S3 operations and improved performance. The work ported the SDK v2 upgrade across two revision targets (7x and 8x), with commits dfbdf851eeadf0b06cfe8368ec21572229c1db56 and c040729ac60aaad7956cdb851c903a5bc39b5277. The changes reduce latency, boost throughput, and position the service for higher concurrency in production. No critical defects were reported; CI and peer reviews were clean, and the work aligns with the roadmap for scalable storage services.

Oct 1, 2025October 2025 – DSpace/DSpace: Delivered high-value feature upgrade and addressed a critical build issue, aligning with business goals to improve storage performance and reliability. Key features delivered: 1) S3 BitStore upgraded to AWS SDK v2 with async operations, CRT client integration, and new throughput/part size/concurrency configuration options. Major bugs fixed: 2) Resolved classpath/resource collision by correcting pom.xml dependency order (dspace-iiif before dspace-api), preventing resource loading conflicts (commits 4f48739116917af5e4e753f73c89573c65d8f8a6 and abd67da44e058ef59f5ad4712b0e66bd4895101c). Overall impact and accomplishments: 3) Improved storage throughput and reliability for large bitstreams, reduced classpath-related failures, and strengthened build stability to support further modernization efforts. Technologies/skills demonstrated: Java, AWS SDK v2, CRT client, asynchronous I/O, Maven dependency management, and system-level integration between storage components.
