Update database
You can use the following code snippets to update your databases.
Note
These code snippets are based on full sample applications on GitHub
- Java
-
public void updateDatabase(String kmsId) { System.out.println("Updating kmsId to " + kmsId); UpdateDatabaseRequest request = new UpdateDatabaseRequest(); request.setDatabaseName(DATABASE_NAME); request.setKmsKeyId(kmsId); try { UpdateDatabaseResult result = amazonTimestreamWrite.updateDatabase(request); System.out.println("Update Database complete"); } catch (final ValidationException e) { System.out.println("Update database failed:"); e.printStackTrace(); } catch (final ResourceNotFoundException e) { System.out.println("Database " + DATABASE_NAME + " doesn't exist = " + e); } catch (final Exception e) { System.out.println("Could not update Database " + DATABASE_NAME + " = " + e); throw e; } }
- Java v2
-
public void updateDatabase(String kmsKeyId) { if (kmsKeyId == null) { System.out.println("Skipping UpdateDatabase because KmsKeyId was not given"); return; } System.out.println("Updating database"); UpdateDatabaseRequest request = UpdateDatabaseRequest.builder() .databaseName(DATABASE_NAME) .kmsKeyId(kmsKeyId) .build(); try { timestreamWriteClient.updateDatabase(request); System.out.println("Database [" + DATABASE_NAME + "] updated successfully with kmsKeyId " + kmsKeyId); } catch (ResourceNotFoundException e) { System.out.println("Database [" + DATABASE_NAME + "] does not exist. Skipping UpdateDatabase"); } catch (Exception e) { System.out.println("UpdateDatabase failed: " + e); } }
- Go
-
// Update Database. updateDatabaseInput := ×treamwrite.UpdateDatabaseInput { DatabaseName: aws.String(*databaseName), KmsKeyId: aws.String(*kmsKeyId), } updateDatabaseOutput, err := writeSvc.UpdateDatabase(updateDatabaseInput) if err != nil { fmt.Println("Error:") fmt.Println(err) } else { fmt.Println("Update database is successful, below is the output:") fmt.Println(updateDatabaseOutput) }
- Python
-
def update_database(self, kms_id): print("Updating database") try: result = self.client.update_database(DatabaseName=Constant.DATABASE_NAME, KmsKeyId=kms_id) print("Database [%s] was updated to use kms [%s] successfully" % (Constant.DATABASE_NAME, result['Database']['KmsKeyId'])) except self.client.exceptions.ResourceNotFoundException: print("Database doesn't exist") except Exception as err: print("Update database failed:", err)

The following snippet uses AWS SDK for JavaScript v3. For more information about how to install the client and usage, see Timestream Write Client - AWS SDK for JavaScript v3.
Also see Class UpdateDatabaseCommand and UpdateDatabase.
import { TimestreamWriteClient, UpdateDatabaseCommand } from "@aws-sdk/client-timestream-write"; const writeClient = new TimestreamWriteClient({ region: "us-east-1" }); let updatedKmsKeyId = "
<updatedKmsKeyId>
"; const params = { DatabaseName: "testDbFromNode", KmsKeyId: updatedKmsKeyId }; const command = new UpdateDatabaseCommand(params); try { const data = await writeClient.send(command); console.log(`Database ${data.Database.DatabaseName} updated kmsKeyId to ${updatedKmsKeyId}`); } catch (error) { if (error.code === 'ResourceNotFoundException') { console.log("Database doesn't exist."); } else { console.log("Update database failed.", error); } }The following snippet uses the AWS SDK for JavaScript V2 style. It is based on the sample application at Node.js sample Amazon Timestream for LiveAnalytics application on GitHub
