You should be able to set up both a harddisk and memory HDF5 file and make
external links from one to the other and vice versa. Would that do the job?

Does HDF5 support construction of a virtual HDF5 file composed of both local

possibly through the use of the H5FD_FAMILY driver?
Application

HDF5 Virtual File Layer (VLF)
( H5FD_FAMILY )

H5FD_CORE H5FD_STDIO

Memory Hard Drive
I also would like to create an HDF5 file that has a small and fast memory
cache for incoming live data and periodically write its contents to storage
for longer term retrieval.
It is not clear to me through the documentation whether the H5FD_FAMILY is
only applicable to combining local disk (i.e. Hard Drive) based file
drivers.
The goal that I'm shooting for is seamless access across both a memory-based
file and one that is stored on a hard disk.
