A client for using the Data API. This is the main entry point and sits

token: an Access Token to the database. Example: `"AstraCS:xyz..."`.
This can be either a literal token string or a subclass of

environment: a string representing the target Data API environment.
It can be left unspecified for the default value of `Environment.PROD`;

database must be located in that region.
The region cannot be specified when the API endoint is used as `id`.
Note that if this parameter is not passed, and cannot be inferred

-
Get a Database object from this client, for doing data-related work.
Args
id
- the target database ID or the corresponding API Endpoint. The database must exist already for the resulting object to be effectively used; in other words, this invocation does not create the database, just the object instance. Actual admin work can be achieved by using the AstraDBAdmin object.
api_endpoint
- a named alias for the
id
first (positional) parameter, with the same meaning. It cannot be passed together withid
. token
- if supplied, is passed to the Database instead of the client token.
This can be either a literal token string or a subclass of
TokenProvider
. namespace
- if provided, it is passed to the Database; otherwise the Database class will apply an environment-specific default.
region
- the region to use for connecting to the database. The
database must be located in that region.
The region cannot be specified when the API endoint is used as
id
. Note that if this parameter is not passed, and cannot be inferred from the API endpoint, an additional DevOps API request is made to determine the default region and use it subsequently. api_path
- path to append to the API Endpoint. In typical usage, this should be left to its default of "/api/json".
api_version
- version specifier to append to the API path. In typical usage, this should be left to its default of "v1".
max_time_ms
- a timeout, in milliseconds, for the DevOps API
HTTP request should it be necessary (see the
region
argument).
Returns
a Database object with which to work on Data API collections.
Example
>>> my_db0 = my_client.get_database("01234567-...") >>> my_db1 = my_client.get_database( ... "https://01234567-...us-west1.apps.astra.datastax.com", ... ) >>> my_db2 = my_client.get_database("01234567-...", token="AstraCS:...") >>> my_db3 = my_client.get_database("01234567-...", region="us-west1") >>> my_coll = my_db0.create_collection("movies", dimension=2) >>> my_coll.insert_one({"title": "The Title", "$vector": [0.3, 0.4]})
