Developed a flexible transaction timeout feature for the ytsaurus/ytsaurus repository, enabling client applications to specify custom transaction durations through the Go SDK. This work involved extending the BeginTx function to accept StartTxOptions-based timeout parameters, allowing for more reliable handling of long-running workflows and reducing failures caused by fixed timeouts. The implementation was delivered as a dedicated commit with comprehensive changelog updates and release-notes guidance to support maintainability. Leveraging Go and backend development expertise, the solution improved transaction configurability and aligned the SDK’s behavior with real-world usage patterns, enhancing the overall reliability of transaction management in distributed systems.
