Concurrent download of multiple files

[LucaMaurelliC]

I am wondering whether it is possible to use the library to download multiple files in parallel/concurrently (i.e. by exploiting asyncio Python SDK for Azure Blob Storage) so that given a list of files, e.g. ["file1.parquet", "file2.parquet", "file3.parquet"] I can start the download of all files in parallel with couritines and await them so that at the end I can do something the files, e.g. for instance concatenating them together.

What I tried so far is a single file:

import pandas as pd
storage_options={"connection_string": "MY_CONNECTION_STRING"}
CONTAINER = "MY_CONTAINER_NAME"
FILE = "PATH/TO/FILE.parquet"
FILEPATH = f"az:https://{CONTAINER}/{FILE}"
df = pd.read_parquet(FILEPATH, storage_options=storage_options)

adlfs (like most fsspec libraries) is asynchronous internally with a sync API on top. See https://filesystem-spec.readthedocs.io/en/latest/async.html for more.
