Realiza sondeos para elementos sin reservar de la cola de indexación y marca un conjunto como reservado, comenzando por los elementos que tienen la marca de tiempo más antigua de la ItemStatus de prioridad más alta. El orden de prioridad es el siguiente:
La reserva de elementos garantiza que la sondeo de otros subprocesos no pueda crear conjuntos superpuestos.
Después de controlar los elementos reservados, el cliente debe volver a colocarlos en el estado no reservado, ya sea llamando a index, o a push con el tipo REQUEUE..
Los elementos estarán disponibles automáticamente (sin reservar) después de 4 horas, incluso si no se llama a ningún método de actualización o push.
Esta API requiere una cuenta de administrador o de servicio para ejecutarse. La cuenta de servicio que se usa es la que se incluye en la lista de entidades permitidas de la fuente de datos correspondiente.
Solicitud HTTP
POST https://cloudsearch.googleapis.com/v1/indexing/{name=datasources/*}/items:poll
Limita los elementos sondeados a los que tienen estos estados.
limit
integer
Es la cantidad máxima de elementos que se mostrarán.
El valor máximo es 100 y el valor predeterminado es 20.
queue
string
Es el nombre de la fila desde la que se recuperarán los elementos. Si no se especifica, items.poll recuperará datos de la cola "default". La longitud máxima es de 100 caracteres.
