Explore loading speed and subsetting for global orca domain #626

Open b-barton opened 11 months ago

b-barton commented 11 months ago

Loading global data and taking a subset for computing heat content on 1 year of data takes varying time according to the method:

with COAsT it took over 1h15 (it actually didn't finish because of a bug),
with Xarray and the preprocessing partial function it took 12m55,
with Dask it took 6m47.

Does this bug in (1) still exist? Investigate feasibility of implementing speed ups in COAsT.

AC:

Create ticket for bug
Propose ticket for speeding up COAsT users (ideally a solution using COAsT.gridded() but worse case e.g. just ADDITIONAL documentation about how to use Dask.
