Após criar uma
fila pull, é
possível criar tarefas e adicioná-las a essa fila.

da fila, que é definido em
queue.xml.
Em seguida use o builder e TaskOptions.Method.PULL para adicionar a tarefa.
O exemplo a seguir coloca tarefas em uma fila pull chamada pull-queue:
Primeiro, receba a fila usando o nome definido no queue.xml
Em seguida, use o método add() da fila com TaskOptions.Method.PULL para colocar
tarefas em uma fila pull chamada pull-queue:
