Databases reference

You can use the Data API clients and the Astra CLI to perform certain administrative operations on your Astra DB Serverless databases and namespaces. For broader administration, such as user management, use the Astra Portal or the DevOps API.

To perform administrative operations, the Data API clients use specific classes:

  • The Astra DB Admin class works at the level of databases, such as to create a database.

  • The Database Admin class works within a specific database, such as to create a namespace.

To perform database operations, you need a token with permission to create and configure databases, such as the Organization Administrator role.

Get an Astra DB Admin

Use the Astra DB Admin object to work at the database level. Use the client to create the Astra DB Admin.

The object name varies by client language. For Python and Java, it is AstraDBAdmin. For TypeScript, it is AstraAdmin.

  • Python

  • TypeScript

  • Java

  • CLI

For more information, see the API reference.

admin = client.get_admin()

Parameters:

Name Type Summary

token

Optional[str]

If supplied, is passed to the Astra DB Admin instead of the client token. This may be useful when switching to a more powerful, admin-capable permission set.

Returns:

AstraDBAdmin - An object used for database-level administrative tasks.

Example response
AstraDBAdmin("AstraCS:aAbB...")

Example:

from astrapy import DataAPIClient
client = DataAPIClient("TOKEN")
admin = client.get_admin()
databases = admin.list_databases()
new_db_admin = admin.create_database(
    "the_other_database",
    cloud_provider="AWS",
    region="eu-west-1",
)
new_db_admin.list_namespaces()
# ['default_keyspace', 'that_other_one']

For more information, see the API reference.

const admin = client.admin();

Parameters:

Name Type Summary

options?

AdminSpawnOptions

The options to use for the admin

Options (AdminSpawnOptions):

Name Type Summary

adminToken?

string

Access token to use for the admin. Default is the client’s token. Typically, of the form 'AstraCS:…​'.

monitorCommands?

boolean

Whether to monitor admin commands through AdminCommandEvents, using the client as an event emitter. Defaults to false.

endpointUrl?

string

Base URL for the DevOps API

Returns:

AstraAdmin - An object used for database-management-level administrative tasks.

Example:

import { DataAPIClient } from '@datastax/astra-db-ts'

const client = new DataAPIClient('TOKEN');

// Spawn an AstraAdmin instance
const admin = client.admin();

(async function () {
  // List all non-terminated databases
  console.log(await admin.listDatabases());

  // Create an actual new database
  const newDbAdmin = await admin.createDatabase({
    name: 'the_other_database',
    cloudProvider: 'aws',
    region: 'eu-west-1',
  });

  // Prints ['default_keyspace']
  console.log(await newDbAdmin.listNamespaces());
})();

For more information, see the API reference.

// Given 'client' an instance of 'DataAPIClient'
AstraDBAdmin admin = client.getAdmin();
AstraDBAdmin admin = client.getAdmin("token");

Returns:

AstraDBAdmin - An object used for database-level administrative tasks in Astra DB Serverless.

Parameters:

Name Type Summary

token

String

If provided, this optional token is passed to the Astra DB Admin instead of the client’s token. You can use this to switch to a different permission set than that offered by the client’s token.

Example:

package com.datastax.astra.client;


import com.datastax.astra.client.admin.AstraDBAdmin;

import static com.dtsx.astra.sdk.db.domain.CloudProviderType.GCP;

public class ConnectingAdmin {
    public static void main(String[] args) {
        // Default Initialization
        DataAPIClient client = new DataAPIClient("TOKEN");

        // Accessing admin providing a new token possibly with stronger permissions
        AstraDBAdmin astradbAdmin = client.getAdmin("SUPER_USER_TOKEN");

        // Create a Database
        astradbAdmin.createDatabase("db-demo", GCP, "us-east-1").listNamespaceNames();
    }
}

When you setup Astra CLI, you provide an application token that authorizes you to run the CLI commands.

Create a database

You can create databases in the Astra Portal or programmatically.

  • Python

  • TypeScript

  • Java

  • CLI

For more information, see the API reference.

The database creation is done through an instance of the AstraDBAdmin class.

new_db_admin = admin.create_database(
    "new_database",
    cloud_provider="aws",
    region="ap-south-1",
)

Returns:

AstraDBDatabaseAdmin - A Database Admin object representing the newly-created database.

Example response
AstraDBDatabaseAdmin(id="01234567-89ab-cdef-0123-456789abcdef", "AstraCS:aAbB...")

Parameters:

Name Type Summary

name

str

The desired name for the database.

wait_until_active

bool

If true (default), the method returns only after the new database is in ACTIVE state. If false, it returns immediately after issuing the creation request, and it is the responsibility of the caller to check the database status before working with it.

cloud_provider

str

one of 'aws', 'gcp' or 'azure'.

region

str

any of the available cloud regions.

namespace

Optional[str]

name for the one namespace the database starts with. If omitted, DevOps API will use its default.

max_time_ms

Optional[int]

A timeout, in milliseconds, for the whole requested operation to complete. Note that a timeout is no guarantee that the creation request has not reached the API server.

You can’t use the database until it is created and in an ACTIVE status. By default, the command waits until the database is created and ready to use. You can set wait_until_active to false to skip waiting while the database activates. However, you can’t perform operations on the new database before it is active.

Example:

from astrapy import DataAPIClient
client = DataAPIClient("TOKEN")
admin = client.get_admin()
new_db_admin = admin.create_database(
    "new_database",
    cloud_provider="aws",
    region="ap-south-1",
)
new_db = new_db_admin.get_database()
collection = new_db.create_collection("movies", dimension=5)
collection.insert_one({
    "title": "The Title",
    "$vector": [0.1, 0.3, -0.7, 0.9, -0.1],
})

For more information, see the API reference.

The database creation is done through an instance of the AstraAdmin class.

const newDbAdmin = await admin.createDatabase({
  name: 'new-database',
  region: 'us-east1',
  cloudProvider: 'GCP',
});

Parameters:

Name Type Summary

config

DatabaseConfig

The properties of the database to create.

options?

AdminBlockingOptions

Options regarding the creation of the database.

Config (DatabaseConfig):

Name Type Summary

name

string

Name of the database (non-unique user-friendly identifier)

cloudProvider

DatabaseCloudProvider

Cloud provider where the database lives

region

string

The cloud region where the database is located.

namespace?

string

Overrides the default namespace (keyspace)

Returns:

Promise<AstraDbAdmin> - A promised instance of the AstraDbAdmin class for that database.

Example:

import { DataAPIClient } from '@datastax/astra-db-ts'

// Obtain an admin instance
const admin = new DataAPIClient('TOKEN').admin();

(async function () {
  // Create a new database
  const dbAdmin = await admin.createDatabase({
    name: 'my-database',
    region: 'us-east1',
    cloudProvider: 'GCP',
  });

  // Get and use the database
  const db = dbAdmin.db();
  console.log(await db.listCollections());
})();

You can’t use the database until it is created and in an ACTIVE status. By default, the createDatabase method blocks until the database is active. This entails polling the database status until it is ACTIVE. To disable this behavior, pass { blocking: false } to the options parameter. However, you can’t perform operations on the new database before it is active.

Creating a database is available in the AstraDBAdmin class.

// Given 'admin' a AstraDBAdmin object
DatabaseAdmin new_db_admin1 = admin.createDatabase(String name);
DatabaseAdmin new_db_admin2 = admin.createDatabase(
        String name,
        CloudProviderType cloudProvider,
        String cloudRegion);
DatabaseAdmin new_db_admin = admin.createDatabase(
        String name,
        CloudProviderType cloudProvider,
        String cloudRegion,
        boolean waitUntilActive)

Parameters:

Name Type Summary

name

String

The desired name for the database.

cloudProvider

CloudProviderType

One of 'aws', 'gcp' (default) or 'azure'.

region

String

Any of the available cloud regions (default: 'us-east1').

waitUntilActive

bool

If true (default), the method returns only after the new database is in ACTIVE state. If false, it returns immediately after issuing the creation request, and it is the responsibility of the caller to check the database status before working with it.

Returns:

DatabaseAdmin - An instance of Database administration object.

You can’t use the database until it is created and in an ACTIVE status. By default, the command waits until the database is created and ready to use. You can set waitUntilActive to false to skip waiting while the database activates. However, you can’t perform operations on the new database before it is active.

Example:

package com.datastax.astra.client.admin;

import com.datastax.astra.client.DataAPIClient;
import com.dtsx.astra.sdk.db.domain.CloudProviderType;

public class CreateDatabase {
  public static void main(String[] args) {
    AstraDBAdmin astraDBAdmin = new DataAPIClient("TOKEN").getAdmin();

    // Choose a cloud provider (GCP, AZURE, AWS) and a region
    CloudProviderType cloudProvider = CloudProviderType.GCP;
    String cloudRegion = "us-east1";

    // Create a database
    DatabaseAdmin admin = astraDBAdmin.createDatabase("DATABASE_NAME", cloudProvider, cloudRegion);
  }
}

Create a database:

astra db create DB_NAME --region REGION --cloud CLOUD_PROVIDER \
-k KEYSPACE --if-not-exist --async

Parameters

Options Type Description

db_name

String

The database name.

region

String (OPTIONAL)

The cloud provider region in which to create the database, such as us-west-2.

cloud

String (OPTIONAL)

The cloud provider (gcp,azure,aws) to use for the database.

keyspace

String (OPTIONAL)

The name of the database’s initial namespace. If omitted, the default is default_keyspace.

--if-not-exists

flag (OPTIONAL)

If provided, this makes the operation idempotent. Check for an existing database with the same configuration.

--async

flag (OPTIONAL)

By default, the operation is synchronous and waits for the database to become active. Include this option to make the operation asynchronous.

By default, the command waits until the database is created and ready to use.

You can set --async to skip waiting while the database activates. However, you can’t perform operations on the new database before it is active.

Drop a database

Delete a database and erase all data stored in it.

  • Python

  • TypeScript

  • Java

  • CLI

For more information, see the API reference.

The database deletion is done through an instance of the AstraDBAdmin class.

admin.drop_database("01234567-...")

Parameters:

Name Type Summary

id

str

The ID of the target database.

wait_until_active

bool

If true (default), the method returns only after the database is actually been deleted. If false, it returns immediately after issuing the drop request, and it is the responsibility of the caller to check the database status/availability after that, if desired.

max_time_ms

Optional[int]

A timeout, in milliseconds, for the whole requested operation to complete. Note that a timeout is no guarantee that the deletion request has not reached the API server.

Returns:

Dict - A dictionary in the form {"ok": 1} if the method succeeds.

Example response
{"ok": 1}

Example:

from astrapy import DataAPIClient
client = DataAPIClient("TOKEN")
admin = client.get_admin()

database_list_pre = list(admin.list_databases())
len(database_list_pre)
# 3
admin.drop_database("01234567-...")
# {'ok': 1}
database_list_post = list(admin.list_databases())
len(database_list_post)
# 2

View this topic in more detail on the API Reference.

The database termination is done through an instance of the AstraAdmin class.

await admin.dropDatabase('DB_ID');

Parameters:

Name Type Summary

db

Db | string

The ID of the target database.

options?

AdminBlockingOptions

Options regarding the termination of the database.

Example:

import { DataAPIClient } from '@datastax/astra-db-ts'

const admin = new DataAPIClient('TOKEN').admin();

(async function () {
  await admin.dropDatabase('DB_ID');
})();

By default, the dropDatabase method blocks until the database is deleted. This entails polling the database status until it is TERMINATED. To disable this behavior, pass { blocking: false } to the options parameter.

The delete database function is available in the AstraDBAdmin class.

// Given 'admin', a AstraDBAdmin object
// Delete an existing database by name

import java.util.UUID;

public class DropDatabase {
  public static void main(String[] args) {
    AstraDBAdmin astraDBAdmin = new DataAPIClient("TOKEN").getAdmin();

    // Delete an existing database
    astraDBAdmin.dropDatabase("<database_name>");

    // Delete an existing database by ID
    astraDBAdmin.dropDatabase(UUID.fromString("<database_id>"));

Get a Database Admin

The Database Admin object can perform administrative tasks within a database, such as managing namespaces.

The object name varies by client language:

  • For Python, it is AstraDBDatabaseAdmin.

  • For TypeScript, it is AstraDbAdmin.

  • For Java, it is DatabaseAdmin.

An Astra DB Admin can instantiate one Database Admin object for an existing database.

  • Python

  • TypeScript

  • Java

  • CLI

For more information, see the API reference.

db_admin = admin.get_database_admin("01234567-...")

Parameters:

Name Type Summary

id

str

The ID of the target database.

Returns:

AstraDBDatabaseAdmin - A Database Admin object representing the target database.

Example response
AstraDBDatabaseAdmin(id="01234567-89ab-cdef-0123-456789abcdef", "AstraCS:aAbB...")

Example:

from astrapy import DataAPIClient
client = DataAPIClient("TOKEN")
admin = client.get_admin()

db_admin = admin.get_database_admin("01234567-...")
db_admin.list_namespaces()
# ['default_keyspace']
db_admin.create_namespace("that_other_one")
# {'ok': 1}
db_admin.list_namespaces()
# ['default_keyspace', 'that_other_one']

For more information, see the API reference.

string

The database’s API endpoint, typically formatted as \https://DB_ID-REGION.apps.astra.datastax.com.

dbOptions?

DbSpawnOptions

The options to use for the underlying database (see Connect to a Database for more information). The admin options are taken from the parent admin instance.

Returns:

AstraDbAdmin - An object used for database-specific-level administrative tasks.

Example:

import { DataAPIClient } from '@datastax/astra-db-ts'

// Spawn an AstraDbAdmin instance
const admin = new DataAPIClient('TOKEN').admin();
const dbAdmin = admin.dbAdmin('ENDPOINT');

(async function () {
  // ['default_keyspace']
  console.log(await dbAdmin.listNamespaces());

  await dbAdmin.createNamespace('that_other_one');

  // ['default_keyspace', 'that_other_one']
  console.log(await dbAdmin.listNamespaces());
})();
// Given 'admin', a AstraDBAdmin object
DatabaseAdmin dbAdmin = admin
  .getDatabaseAdmin(UUID.fromString("databaseId"));

Returns:

DatabaseAdmin - An instance of a Database administration object.

Parameters:

Name Type Summary

databaseId

UUID

The ID of the target database for which to create a Database Admin object.

import com.datastax.astra.client.admin.AstraDBAdmin;
import com.datastax.astra.client.admin.DatabaseAdmin;

import java.util.UUID;

public class GetDatabaseAdmin {
    public static void main(String[] args) {
        // Default Initialization
        DataAPIClient client = new DataAPIClient("TOKEN");

        // Accessing admin providing a new token possibly with stronger permissions
        AstraDBAdmin astradbAdmin = client.getAdmin("SUPER_USER_TOKEN");

        DatabaseAdmin admin = astradbAdmin.getDatabaseAdmin(UUID.fromString("<database_id>"));
    }
}

When you setup Astra CLI, you provide an application token that authorizes you to run the CLI commands.

Create a namespace

Databases include an initial default_namespace. You can create more namespaces as needed, such as for better application structure.

  • Python

  • TypeScript

  • Java

  • CLI

For more information, see the API reference.

db_admin.create_namespace("that_other_one")

Parameters:

Name Type Summary

name

str

The namespace name.If supplying a namespace that exists already, the method call proceeds as usual, no errors are raised, and the whole invocation is a no-op.

wait_until_active

Type

If True (default), the method returns only after the target database is in ACTIVE state again (a few seconds, usually). If False, it will return right after issuing the creation request to the DevOps API, and it will be responsibility of the caller to check the database status/namespace availability before working with it.

max_time_ms

Type

A timeout, in milliseconds, for the whole requested operation to complete. Note that a timeout is no guarantee that the creation request has not reached the API server.

Returns:

Dict - A dictionary of the form {"ok": 1} if the operation succeeds. Otherwise, an exception is raised.

Example response
{"ok": 1}

Example:

from astrapy import DataAPIClient
client = DataAPIClient("TOKEN")
db_admin = client.get_admin().get_database_admin("01234567-...")

db_admin.list_namespaces()
# ['default_keyspace']
db_admin.create_namespace("that_other_one")
# {'ok': 1}
db_admin.list_namespaces()
# ['default_keyspace', 'that_other_one']

For more information, see the API reference.

await admin.createNamespace('that_other_one');

Parameters:

Name Type Summary

name

string

The name of the namespace to create.

options?

AdminBlockingOptions

Blocking options regarding the creation of the namespace.

Returns:

Promise<void> - A promise that resolves when the namespace is created (or when the initial request completes if not blocking).

Example:

import { DataAPIClient } from '@datastax/astra-db-ts'

// Spawn an AstraDbAdmin instance
const admin = new DataAPIClient('TOKEN').admin();
const dbAdmin = admin.dbAdmin('ENDPOINT');

(async function () {
  // ['default_keyspace']
  console.log(await dbAdmin.listNamespaces());

  await dbAdmin.createNamespace('that_other_one');

  // ['default_keyspace', 'that_other_one']
  console.log(await dbAdmin.listNamespaces());
})();

The createNamespace method blocks until the database is active, by default. This entails polling the database status until it is ACTIVE. You can disable this behavior by passing { blocking: false } to the options parameter.
