Class StreamConnection
java.lang.Object
com.google.cloud.bigquery.storage.v1beta2.StreamConnection
StreamConnection is responsible for writing requests to a GRPC bidirecional connection.
StreamWriter creates a connection. Two callback functions are necessary: request_callback and done_callback. Request callback is used for every request, and done callback is used to notify the user that the connection is closed and no more callbacks will be received from this connection.
The stream writer will accept all the requests without flow control, and makes the callbacks in receiving order.
It's user's responsibility to do the flow control and maintain the lifetime of the requests.
