Transmisión de informes

Organiza tus páginas con colecciones Guarda y categoriza el contenido según tus preferencias.

Existen tres métodos para recuperar entidades e informar datos con la API de Google Ads.

Esta guía se centra principalmente en los datos de transmisión de GoogleAdsService. A continuación, se detallan las distinciones de alto nivel de los tres métodos de recuperación de datos:

Servicio de Google Ads.SearchStream Servicio de Google Ads Solicitudes GET
Apto para código de producción No (solo para depuración)
Service GoogleAdsService GoogleAdsService Servicios específicos de recursos (por ejemplo, CampaignService)
Situación Recupera informes y objetos Recupera informes y objetos Recupera objetos
Respuesta Flujo de objetos GoogleAdsRow Páginas de los objetos GoogleAdsRow Un objeto (por ejemplo, Campaign)
Campos de la respuesta Solo los especificados en la consulta Solo los especificados en la consulta Todos los campos propagados
Límites diarios Límites diarios según los niveles de acceso Límites diarios según los niveles de acceso 1,000 solicitudes por día

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.

Para 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 quitar el tiempo de red de ida y vuelta necesario para solicitar cada página individual de una respuesta Search, según tu app, SearchStream puede ofrecer un mejor rendimiento en la paginación, en especial para informes más grandes.

Ejemplo

Tomemos como ejemplo un informe que contenga 100,000 filas. En la siguiente tabla, se desglosan las diferencias contables entre los dos métodos.

Flujo de búsqueda Buscar
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 API 1 transmisión continua 10 respuestas

Factores de rendimiento

En general, recomendamos SearchStream en lugar de Search por las siguientes razones.

  • Para los informes de una sola página (menos de 10,000 filas): no hay diferencias de rendimiento significativas entre los dos métodos.

  • En los informes de varias páginas, SearchStream suele ser más rápido, ya que se evitan varias idas y vueltas, y la lectura y escritura desde la caché de disco es menos un factor.

Límites de frecuencia

Los límites diarios de ambos métodos se adhieren a los límites estándar y los niveles de acceso del token del desarrollador. Una consulta o un informe individual se cuentan como una operación, sin importar el resultado que se pagina o se transmite.
