Streaming de relatórios

Há três métodos para recuperar entidades e gerar relatórios de dados com a API Google Ads.

• GoogleAdsService.SearchStream
• GoogleAdsService.Search
• Solicitações GET

Este guia se concentra principalmente no streaming de dados de GoogleAdsService. Veja a seguir as distinções de alto nível dos três métodos de recuperação de dados:

SearchStream x Pesquisa

Embora Search possa enviar várias solicitações paginadas para fazer o download do relatório inteiro, o SearchStream envia uma única solicitação e inicia uma conexão permanente com a API Google Ads, independentemente do tamanho do relatório.

Para SearchStream, o download dos pacotes de dados começa imediatamente com todo o resultado armazenado em cache em um buffer de dados. O código pode começar a ler os dados armazenados em buffer sem ter que esperar que o stream inteiro termine.

Ao eliminar o tempo de rede de ida e volta necessário para solicitar cada página individual de uma resposta Search, dependendo do app, SearchStream pode oferecer um desempenho melhor do que a paginação, especialmente para relatórios maiores.

Exemplo

Veja um relatório que consiste em linhas de 100,000, por exemplo. A tabela a seguir detalha as diferenças contábeis entre os dois métodos.

Fatores de desempenho

Em geral, recomendamos SearchStream em vez de Search pelos seguintes motivos:

• Para relatórios de página única (menos de 10 mil linhas): não há diferenças significativas de desempenho entre os dois métodos.

• Para vários relatórios de página: SearchStream normalmente é mais rápido, porque várias idas e voltas são evitadas e a leitura/gravação do cache de disco é menos importante.

Limites de utilização

Os limites diários para os dois métodos aderem aos limites padrão e aos níveis de acesso do token de desenvolvedor. Uma única consulta ou relatório é contada como uma operação, independentemente do resultado paginado ou transmitido.
