[danielballan]

Use case

from tiled.client import from_profile
import pandas

c = from_profile('local', api_key='secret')
df = pandas.DataFrame({"A": [1,2,3], "B": [4,5,6], "C": [7,8,9]})
c.write_dataframe(df, key="y")

import duckdb
db = duckdb.connect(':memory:')
db.execute('install httpfs; load httpfs;')
db.execute('SELECT * FROM read_parquet("http://localhost:8000/api/v1/asset/bytes/y?id=1&api_key=secret")')  # uses Range header

Starlette has postponed consideration of support for this. It might make sense to vendor a copy of this approach for now: encode/starlette#1999
