We discussed this issue today in our pangeo coffee break. We think the following plan would be good:

  • [ ] Write a function called auto_chunk(variable) which examines a variable for the presence of a chunks attribute in encoding or within the data itself. Returns a new variable with chunked data.
  • [ ] Refactor open_zarr to call this function
  • [ ] Add it also to open_dataset to enable auto-chunking of netCDF and geotiff data

Should we have an option like chunk_size='native', or chunk_size='100MB', with chunks chosen to align with source chunks.
