  • Packing: reducing the precision of the data to quantity-specific levels of precision
    • lossy - by definition
  • Compression: algorithmically processing the data to store a compression representation on storage
    • lossless - by expectation

This ticket is targeting the exploration of the capabilities of XIOS+netCDF+HDF to pack and compress data.

  • Packing Techniques:
    • type coercion to integer with scale_factor & add_offset
    • quantization
  • Compression Algorithms
    • GNU compression with gzip
    • ZStandard compression with zstd
  • Parallelisation
    • client
    • server (needs a fairly recent version of parallel netCDF+HDF)
