On Friday, May 14, 2021, we hosted JP Swinski as he presented the webinar, H5Coro: The HDF5 Cloud-Optimized Read-Only Library. NASA’s migration of science data products and services to AWS has sparked a debate on the best way to access science data stored in the cloud. Given that a large portion of NASA’s science data is in the HDF5 format or one of its derivatives, a growing number of efforts are looking at ways to efficiently access H5 files residing in S3. This presentation describes one of those efforts and argues for the creation of a standardized subset of the HDF5 specification targeting cloud environments. Slide deck https://youtu.be/RuBKDW4TNO4...
