virtualizarr.accessor.VirtualiZarrDatasetAccessor.nbytes

property VirtualiZarrDatasetAccessor.nbytes: int

Size required to hold these references in memory in bytes.

Note this is not the size of the referenced chunks if they were actually loaded into memory, this is only the size of the pointers to the chunk locations. If you were to load the data into memory it would be ~1e6x larger for 1MB chunks.

In-memory (loadable) variables are included in the total using xarray’s normal .nbytes method.
