Stas enhanced the Change Feed Processor in the Azure/azure-sdk-for-java repository by introducing a configurable cap on the number of leases acquired per cycle, addressing scalability and deployment performance under high-load scenarios. Using Java and backend development skills, Stas designed a solution that enables multi-lease acquisition while reducing resource contention and improving throughput predictability. The technical approach focused on concurrency and configuration design, allowing deployments to better manage resource usage. Although the work spanned a single feature over one month, it demonstrated depth in API development and unit testing, resulting in a targeted, impactful improvement to the processor’s scalability.
