Worked on the gravitee-io/gravitee-api-management repository to address resource leaks in policy instance lifecycle management. The solution involved removing internal caching of policy instances within the backend, ensuring that a new policy instance is created for each request while delegating caching responsibilities to a centralized factory. This approach improved memory stability and efficiency, particularly under concurrent API gateway traffic, and reduced the risk of memory leaks. The work focused on backend development and policy management, utilizing Java to implement and test the fix. The change resulted in more predictable performance and simplified lifecycle management for policy instances in the system.
