Connect to a vector-enabled Astra DB Serverless database

Create a file named with the following content:
import os
from astrapy import DataAPIClient
from astrapy.constants import VectorMetric
from astrapy.ids import UUID
from astrapy.exceptions import InsertManyException

# Initialize the client and get a "Database" object
client = DataAPIClient(os.environ["ASTRA_DB_APPLICATION_TOKEN"])
database = client.get_database(os.environ["ASTRA_DB_API_ENDPOINT"])
print(f"* Database: {}\n")
