Existen tres métodos para recuperar entidades y generar informes con los datos mediante la API de Google Ads.
GoogleAdsService.SearchStreamGoogleAdsService.Search- Solicitudes GET
Esta guía se enfoca principalmente en la transmisión de datos desde GoogleAdsService. Estas son las distinciones de alto nivel para los tres métodos de recuperación de datos:
| ServiciodeGoogleAds.SearchStream | ServiciodeAnunciosDeGoogle.Search | Solicitudes GET | |
|---|---|---|---|
| Adecuado para código de producción | Yes | Yes | No (solo para depuración) |
| Servicio | GoogleAdsService |
GoogleAdsService |
Servicios específicos de recursos (por ejemplo, CampaignService) |
| Situación | Recuperando informes y objetos | Recuperando informes y objetos | Recuperando objetos |
| Respuesta | Transmisión de los objetos GoogleAdsRow |
Páginas de objetos GoogleAdsRow |
Un objeto (por ejemplo, Campaign) |
| Campos de la respuesta | Solo aquellos especificados en la consulta | Solo aquellos especificados en la consulta | Se propagaron todos los campos |
| Límites diarios | Límites diarios basados en los niveles de acceso. | Límites diarios basados en los niveles de acceso. | 1,000 solicitudes por día |
SearchStream en comparación con Search
Si bien Search puede enviar varias solicitudes paginadas para descargar el informe completo, SearchStream envía una sola solicitud e inicia una conexión persistente con la API de Google Ads, sin importar el tamaño del informe.
En el caso de SearchStream, los paquetes de datos comienzan a descargarse de inmediato con el resultado completo almacenado en caché en un búfer de datos. Tu código puede comenzar a leer los datos almacenados en búfer sin tener que esperar a que finalice toda la transmisión.
Al eliminar el tiempo de red de ida y vuelta necesario para solicitar a cada página individual de una respuesta de Search, según la app, SearchStream puede ofrecer un mejor rendimiento en comparación con la paginación, especialmente para los informes más grandes.
Ejemplo
Tomemos como ejemplo un informe que tenga 100,000 filas. En la siguiente
tabla, se desglosan las diferencias contables entre los dos métodos.
| SearchStream | Búsqueda | |
|---|---|---|
| Tamaño de la página | No aplicable | 10,000 filas por página |
| Cantidad de solicitudes a la API | 1 solicitud | 10 solicitudes |
| Cantidad de respuestas de la API | 1 transmisión continua | 10 respuestas |
Factores de rendimiento
En general, recomendamos SearchStream por sobre Search por los siguientes motivos.
Para los informes de una sola página (menos de 10,000 filas): No hay diferencias de rendimiento significativas entre los dos métodos.
En el caso de informes de varias páginas, por lo general,
SearchStreames más rápido, ya que se evitan varios recorridos y la lectura y escritura de la caché de disco es menos que un factor.
Límites de frecuencia
Los límites diarios de ambos métodos cumplen con los límites estándar y los niveles de acceso de tu token de desarrollador. Una única consulta o informe se cuenta como una operación, independientemente del resultado paginado o transmitido.
