Aggiorna database
È possibile utilizzare i seguenti frammenti di codice per aggiornare i database.
Nota
Questi frammenti di codice si basano su applicazioni di esempio complete su. 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

Si basa sull'applicazione di esempio disponibile in Node.js, esempio Amazon Timestream LiveAnalytics
