Worked on the temporalio/temporal repository to develop and deliver a Poller Timeout Jitter Mechanism aimed at improving system stability under high poller counts. This feature introduced randomized jitter to poller context timeouts, effectively desynchronizing poller operations and reducing the risk of simultaneous load spikes. The implementation was carried out using Go, with a focus on backend development practices and robust unit testing. The work included targeted unit tests to validate the jitter behavior, complemented by manual validation through local builds. As a result, the system now exhibits more predictable timeout behavior and enhanced resilience during periods of heavy load.
