Create a keyspace

Creates a new keyspace in a database.

Keyspaces are used to store collections and tables in Hyper-Converged Database (HCD).

Result

  • Python

  • TypeScript

  • Java

  • curl

Creates the specified keyspace.

Does not return anything.

Creates the specified keyspace.

Returns a promise that resolves once the operation completes.

Creates the specified keyspace.

Does not return anything.

Creates the specified keyspace.

If the command succeeds, the response indicates the success.

Example successful response:

{
  "status": {
    "ok": 1
  }
}

Parameters

  • Python

  • TypeScript

  • Java

  • curl

Use the create_keyspace method, which belongs to the astrapy.DataAPIDatabaseAdmin class.

Method signature 
create_keyspace(
  name: str,
  *,
  replication_options: dict[str, Any],
  update_db_keyspace: bool,
  keyspace_admin_timeout_ms: int,
  request_timeout_ms: int,
  timeout_ms: int,
  **kwargs: Any,
) -> None
Name Type Summary

name

str

The name of the keyspace to create.

If a keyspace with the name already exists, a new keyspace isn’t created, and the command succeeds.

replication_options

dict[str, Any]

Optional. Specifies the options for keyspace replication across database nodes.

The structure must be similar to: {"class": "SimpleStrategy", "replication_factor": 1}.

update_db_keyspace

bool

Optional. Whether to set the working keyspace of the Database or AsyncDatabase object that created the current DataAPIDatabaseAdmin object to the new keyspace.

keyspace_admin_timeout_ms

int

Optional. A timeout, in milliseconds, to impose on the underlying API request. If not provided, the DataAPIDatabaseAdmin defaults apply.

This parameter is aliased as request_timeout_ms and timeout_ms for convenience.

Use the createKeyspace method, which belongs to the DataAPIDbAdmin class.

Method signature 
async createKeyspace(
  keyspace: string,
  options?: {
    replication?: KeyspaceReplicationOptions,
    updateDbKeyspace?: boolean,
    timeout?: number | TimeoutDescriptor,
  }
): void
Name Type Summary

keyspace

string

The name of the keyspace to create.

If a keyspace with the name already exists, a new keyspace isn’t created, and the command succeeds.

options

CreateDataAPIKeyspaceOptions

Optional. The options for this operation. See Properties of options for more details.
Properties of options
Name Type Summary

replication

KeyspaceReplicationOptions

Optional. Specifies the options for keyspace replication across database nodes.

Default: {class: 'SimpleStrategy', replicationFactor: 1}

updateDbKeyspace

boolean

Optional. Whether to set the working keyspace of the Db object that created the current DbAdmin object to the new keyspace.

timeout

number | TimeoutDescriptor

Optional.

The timeout(s) to apply to this method. You can specify requestTimeoutMs and keyspaceAdminTimeoutMs.

Details about the timeout parameter

The TimeoutDescriptor object can contain these properties:

  • requestTimeoutMs (number): The maximum time, in milliseconds, that the client should wait for each underlying HTTP request.

    Default: The default value for the admin object. This default is 10 seconds unless you specified a different default when you initialized the DataAPIDbAdmin or DataAPIClient object.

  • keyspaceAdminTimeoutMs (number): The maximum time, in milliseconds, for keyspace admin operations like creating, dropping, and listing keyspaces.

    Default: The default value for the admin object. This default is 30 seconds unless you specified a different default when you initialized the DataAPIDbAdmin or DataAPIClient object.

If you specify a number instead of a TimeoutDescriptor object, that number will be applied to both requestTimeoutMs and keyspaceAdminTimeoutMs.

Use the createKeyspace method, which belongs to the com.datastax.astra.client.admin.DatabaseAdmin class.

Method signature 
void createKeyspace(String keyspaceName)
void createKeyspace(KeyspaceDefinition keyspaceDefinition)
