Use DeleteKeyspace with an Amazon SDK or CLI
The following code examples show how to use DeleteKeyspace.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in
context in the following code example:
- .NET
-
- Amazon SDK for .NET
-
/// <summary>
/// Delete an existing keyspace.
/// </summary>
/// <param name="keyspaceName"></param>
/// <returns>A Boolean value indicating the success of the action.</returns>
public async Task<bool> DeleteKeyspace(string keyspaceName)
{
var response = await _amazonKeyspaces.DeleteKeyspaceAsync(
new DeleteKeyspaceRequest { KeyspaceName = keyspaceName });
return response.HttpStatusCode == HttpStatusCode.OK;
}
- Java
-
- SDK for Java 2.x
-
public static void deleteKeyspace(KeyspacesClient keyClient, String keyspaceName) {
try {
DeleteKeyspaceRequest deleteKeyspaceRequest = DeleteKeyspaceRequest.builder()
.keyspaceName(keyspaceName)
.build();
keyClient.deleteKeyspace(deleteKeyspaceRequest);
} catch (KeyspacesException e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
}

suspend fun deleteKeyspace(keyspaceNameVal: String?) {
val deleteKeyspaceRequest =
DeleteKeyspaceRequest {
keyspaceName = keyspaceNameVal
}
KeyspacesClient { region = "us-east-1" }.use { keyClient ->
keyClient.deleteKeyspace(deleteKeyspaceRequest)
}
}
