Developed intra-stage checkpointing and resume support for the OpenMontage pipeline, focusing on enhancing reliability for long-running data workflows. The solution introduced write and read checkpoints at stage boundaries, allowing processes to recover from failures and resume from the last successful state, thereby reducing downtime and unnecessary reprocessing. This feature was implemented in Python and leveraged backend development and API integration skills to ensure seamless orchestration within the pipeline. The work addressed fault tolerance and improved adherence to service level agreements, resulting in faster recovery and cost savings by avoiding full pipeline reruns. No bugs were reported or fixed during this period.
