Regression in DataArrays created from Pandas

I'm a bit lost what's (not) recommended to use in xarray as coordinate or value. 1.) Can I use numpy StringDType as value? Can I use it as coordinate? 2.)...

Vibe coded benchmark (sorry): ```python import shutil import time from pathlib import Path import statistics import duckdb from pyiceberg.catalog import load_catalog from pyiceberg.schema import Schema from pyiceberg.types import DoubleType, NestedField...
