Adrian Mccague

Worked on the ktorio/ktor repository to deliver two backend features focused on HTTP server customization and concurrency management. Enabled direct configuration of Jetty’s HttpConfiguration within Ktor, allowing deployments to fine-tune HTTP-specific settings such as request header size, which improved flexibility for environments with strict requirements. Later, implemented dynamic thread pool expansion and a rejected execution handler for the Ktor Jetty handler, enhancing reliability and scalability under load, especially for Jakarta deployments. Both features were supported by targeted unit tests to ensure robustness. The work leveraged Java and Kotlin, with a strong emphasis on backend development, server configuration, and concurrency.

December 2025 monthly summary focusing on delivering scalable concurrency and reliability improvements for the Ktor project. Implemented dynamic thread pool expansion for the Ktor Jetty handler to better cope with load spikes, and added a rejected-execution handler to improve resource management during shutdown. Included automated tests confirming the thread pool can expand beyond the configured size when blocking handlers are present, ensuring robustness in Jakarta deployments.

Month: March 2025 — Focused on enabling fine-grained HTTP server customization in ktorio/ktor by exposing JettyHttpConfiguration to Ktor, allowing direct configuration of HTTP-specific settings (e.g., request header size) for deployments with specific constraints. This feature, supported by targeted tests, reduces the need for workaround patches and improves deployment flexibility. No major bugs fixed this month; work concentrated on feature delivery with clear business value and traceability to the commit implementing the change.
