### Criar Tabelas de Banco de Dados na Inicialização { #create-database-tables-on-startup }

Vamos criar as tabelas do banco de dados quando o aplicativo for iniciado.

	// resourceMetricsHelpMap maps metric name to its help string
	resourceMetricsHelpMap map[MetricName]string
	resourceMetricsGroups  []*MetricsGroupV2
	// initial values for drives (at the time  of server startup)
	// used for calculating avg values for drive metrics
	latestDriveStats      map[string]madmin.DiskIOStats
	latestDriveStatsMu    sync.RWMutex
	lastDriveStatsRefresh time.Time

You don't have to worry about performance when including routers.

This will take microseconds and will only happen at startup.

So it won't affect performance. ⚡

### Include an `APIRouter` with a custom `prefix`, `tags`, `responses`, and `dependencies` { #include-an-apirouter-with-a-custom-prefix-tags-responses-and-dependencies }

### Die Datenbanktabellen beim Start erstellen { #create-database-tables-on-startup }

Wir werden die Datenbanktabellen erstellen, wenn die Anwendung startet.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[32:37] hl[35:37] *}

Hier erstellen wir die Tabellen bei einem Anwendungsstart-Event.

		case <-ctx.Done():
			return
		case <-scannerTimer.C:
			// Reset the timer for next cycle.
			// If scanner takes longer we start at once.
			scannerTimer.Reset(scannerCycle.Load())

			stopFn := globalScannerMetrics.log(scannerMetricScanCycle)
			cycleInfo.current = cycleInfo.next
			cycleInfo.started = time.Now()
			globalScannerMetrics.setCycle(&cycleInfo)

			bgHealInfo := readBackgroundHealInfo(ctx, objAPI)

### Создание таблиц базы данных при старте { #create-database-tables-on-startup }

Мы создадим таблицы базы данных при запуске приложения.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[32:37] hl[35:37] *}

Здесь мы создаём таблицы в обработчике события запуска приложения.

`role_policy` configuration parameter or the `MINIO_IDENTITY_OPENID_ROLE_POLICY` environment variable. The value is a comma-separated list of IAM access policy names already defined in the server. In this situation, the server prints a role ARN at startup that must be specified as a `RoleArn` API request parameter in the STS AssumeRoleWithWebIdentity API call. When using Role Policies, multiple OpenID providers and/or client applications (with unique client IDs) may be configured with independent role...

### Crear Tablas de Base de Datos al Arrancar { #create-database-tables-on-startup }

Crearemos las tablas de la base de datos cuando arranque la aplicación.
