Compare Data API client versions
DataStax recommends using the latest versions of the clients to access the newest features, improvements, and bug fixes.

Version 1.5
DataStax released clients version 1.5 and Data API version 1.0.16 on September 20, 2024.
Version 1.5 of the Data API clients deprecates namespace in favor of keyspace.
In this version, you can use either keyspace or namespace, but you must use one consistently.
This change also applies to the Data API itself (HTTP).
This change aligns the Data API and clients with the DevOps API, which already uses keyspace for both namespaces and keyspaces.
It also better reflects the underlying Astra DB functionality, in which namespace is effectively an alternative label for keyspace.

A future client release after version 1.5 will remove support for |
After you upgrade to version 1.5, change your code to use keyspace instead of namespace.
For example:
-
Python
-
TypeScript
-
Java
-
curl
# Before 1.5
database = client.get_database("API_ENDPOINT", namespace="NAMESPACE_OR_KEYSPACE_NAME")
# 1.5 and later
database = client.get_database("API_ENDPOINT", keyspace="NAMESPACE_OR_KEYSPACE_NAME")// Before 1.5
const db = client.db('API_ENDPOINT', { namespace: 'NAMESPACE_OR_KEYSPACE_NAME' });
// 1.5 and later
const db = client.db('API_ENDPOINT', { keyspace: 'NAMESPACE_OR_KEYSPACE_NAME' });// Before 1.5
Database db = client.getDatabase(String apiEndpoint, String namespace);
// 1.5 and later
Database db = client.getDatabase(String apiEndpoint, String keyspace);The impact to HTTP requests is minimal.
HTTP already accepted either a keyspace or namespace name in the URL path, and most commands used a keyspace parameter.
curl -sS --location -X POST "ASTRA_DB_ENDPOINT/api/json/v1/NAMESPACE_OR_KEYSPACE_NAME" \
--header "Token: APPLICATION_TOKEN" \
--header "Content-Type: application/json" \
--data '{DATA_API_COMMAND_BODY}'Astra DB Serverless documentation and client references use keyspace in place of namespace, with the following exceptions:
-
Documentation describing the Astra Portal, which will continue to use
namespace. -
Some preexisting integration guides and tutorials that rely on a subcomponent, such as a sample app, that is unrelated to the Data API and has a
namespaceobject, class, variable, or otherwise. -
Third-party documentation over which DataStax has no influence.
