Hi,
We are prototyping spitting a large hdf5 file into multiple h5 files by using Virtual Data Sets. For our application, we need to return an error in case the caller tries to read data from a VDS and some of the referenced files that store the requested data are not available.
For example, consider a VDS contains a 3 rows and the VDS splits data by rows, Assume the refenced files for row 1 and 2 are available but the file containing rows 3 is not available.
We would like to read data with any chunk size from chunks containing data from rows 1 and 2 and get an error when trying to read data from chunks containing data from row 3 (for example, if reading data by columns with chunks 1x3).
Is it possible to specify either when creating the VDS or when opening a hdf5 for reading that HDF5 library should return an error for missing data from VDS files rather than using the VDS fill value?
Thanks,
Bogdan
