Usage: xcube chunk [OPTIONS] CUBE

  (Re-)chunk xcube dataset. Changes the external chunking of all variables
  of CUBE according to CHUNKS and writes the result to OUTPUT.

  Note: There is a possibly more efficient way to (re-)chunk datasets
  through the dedicated tool "rechunker", see

  -o, --output OUTPUT  Output path. Defaults to 'out.zarr'
  -f, --format FORMAT  Format of the output. If not given, guessed from
  -p, --params PARAMS  Parameters specific for the output format. Comma-
                       separated list of <key>=<value> pairs.
  -C, --chunks CHUNKS  Chunk sizes for each dimension. Comma-separated list of
                       <dim>=<size> pairs, e.g. "time=1,lat=270,lon=270"
  --help               Show this message and exit.


$ xcube chunk input_not_chunked.zarr -o output_rechunked.zarr --chunks "time=1,lat=270,lon=270"
