I’m currently extending the Golang binding of HDF5 because of a special use case which I want to try out (you can see my code here). The goal is to introduce the H5DOwrite_chunk and H5DOread_chunk to the gonum package.
Technically they work, but to be useful I also have to set a filter on the dataset, because my data is arriving pre-compressed (hence the write chunk). But, when I set the filter of the dataset it complains that the filter is not registered, which it isn’t.
#013: H5Z.c line 1205 in H5Z_find(): required filter 32008 is not registered
However, I don’t have the implementation of the filter (bitshuffle + lz4 in my case), but I also don’t need it. My Golang application wont be the one reading the data, I just intend to write the chunk that is given to me, but it looks like I can’t create the dataset with the correct properties.
Is this the case? That I can’t create a dataset with a filter that I don’t have?
