有人在使用Google PubSub服务时知道如何增加io.grpc maxMessageSize吗？
现在当我收到一条大信息时，我有时会遇到这个例外：

该应用程序是用java编写的，使用http://googlecloudplatform.github.io/google-cloud-java/0.6.0/apidocs/index.html?com/google/cloud/pubsub/PubSub.html并在Google Compute Engine实例中运行。

您可以通过NettyChannelBuilder.maxMessageSize()。
在grpc v1.1中，您将能够使用ManagedChannelBuilder.maxInboundMessageSize()并避免直接使用NettyChannelBuilder。您还可以在withMaxInboundMessageSize()和CallOptions上使用AbstractStub按每次通话配置它。
