With a growing demand on HPSS S3 support from SLAC science user’s community, we eagerly started testing HPSS S3 interface since the pre-GA release in July 2023. From the initial fragile and immature version to today’s more robust and resilient state, we worked directly with HPSS S3 developer’s team to troubleshoot and triage many challenging issues faced with the scalability, data IO performance and the large and deeply nested data structure handling for very small files from Rubin LFA ceph S3 store use case.
