Please Help! Unfortunately, AI doesn’t know how to do this.

In the HDF5 file, I need to prepare space for a 3d matrix 4500x9000x10000 Int64 to dynamically write and read data in different planes. The most frequently read portion of data will be the xy matrix, i.e. 4500x9000. How to prepare such a file?

I think you just set the chunk size appropriately ((4500, 9000, 1) maybe) as described in Home · HDF5.jl.
