I will show you some of the main concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).

var baseErrs = []error{
	errDiskNotFound,
	errFaultyDisk,
	errFaultyRemoteDisk,
}

var baseIgnoredErrs = baseErrs

// Is a one place function which converts all os.PathError
// into a more FS object layer friendly form, converts
// known errors into their typed form for top level
// interpretation.
func osErrToFileErr(err error) error {
	if err == nil {
		return nil
	}
	if osIsNotExist(err) {

        final OptionalEntity<SearchResponse> searchResponseOpt = sendRequest(query, params, userBean);
        return processResponse(searchResponseOpt);
    }

    /**
     * Processes the OpenSearch response and converts it to a SearchResult.
     *
     * @param searchResponseOpt the optional search response from OpenSearch
     * @return the processed search result
     */

Al desplegar aplicaciones probablemente querrás tener algo de **replicación de procesos** para aprovechar **múltiples núcleos** y poder manejar más requests.

Como viste en el capítulo anterior sobre [Conceptos de Despliegue](concepts.md){.internal-link target=_blank}, hay múltiples estrategias que puedes usar.

Aquí te mostraré cómo usar **Uvicorn** con **worker processes** usando el comando `fastapi` o el comando `uvicorn` directamente.

    /**
     * Gets the version number for this search log event.
     *
     * @return The version number, or null if not versioned
     */
    Long getVersionNo();

    /**
     * Converts this search log event to a source map for indexing or logging.
     *
     * @return Map representation of the event data
     */
    Map<String, Object> toSource();

    /**

        final int pos = str.lastIndexOf(separator);
        if (pos == -1) {
            return str;
        }
        return str.substring(pos + 1, str.length());
    }

    /**
     * Converts a byte array to a hexadecimal string.
     *
     * @param bytes
     *            the byte array
     * @return the hexadecimal string
     */
    public static String toHex(final byte[] bytes) {

	h.mu.RLock()
	defer h.mu.RUnlock()

	b, err := json.MarshalIndent(h, "", "  ")
	if err != nil {
		writer.Write([]byte(err.Error()))
		return
	}
	writer.Write(b)
}

// toHealingDisk converts the information to madmin.HealingDisk
func (h *healingTracker) toHealingDisk() madmin.HealingDisk {
	h.mu.RLock()
	defer h.mu.RUnlock()

	return madmin.HealingDisk{
		ID:                h.ID,

* `datetime.timedelta`:
    * Pythonの`datetime.timedelta`です。
    * リクエストとレスポンスでは合計秒数の`float`で表現されます。
    * Pydanticでは「ISO 8601 time diff encoding」として表現することも可能です。<a href="https://docs.pydantic.dev/latest/concepts/serialization/" class="external-link" target="_blank">詳細はドキュメントを参照してください</a>。
* `frozenset`:
    * リクエストとレスポンスでは`set`と同じように扱われます:
        * リクエストでは、リストが読み込まれ、重複を排除して`set`に変換されます。
        * レスポンスでは`set`が`list`に変換されます。
