In March 2026, Jojo Sneg developed a configurable HeapShrinker feature for the envoyproxy/envoy repository, enabling operators to fine-tune memory management through custom timer intervals and memory thresholds. Using C++ and focusing on system configuration and memory management, Jojo introduced the ShrinkHeapConfig, updated proto definitions, and integrated the new settings into the Overload Manager’s typed_config parsing. The work included comprehensive unit tests to ensure correct parsing and error handling, as well as thorough documentation and release notes. By preserving backward compatibility and making the feature opt-in, Jojo delivered a robust, flexible solution tailored for dynamic deployment environments.
