Hi all, I am working in a research project at Brandeis University which aims to provide snapshot support in the HDF5 file system. The idea is to use Berkeley DB with snapshot support to store the HDF5 metadata. I was wondering what is the more efficient and modular way to do it, instead of modifying the core code of HDF5. Is there a way to replace the standard VOL (or VFL) responsible for writing the data and metadata on disk with a new VOL which will not write the metadata in regular format, but send it to Berkeley DB instead?
Thanks a lot in advance, Dimos
