One option is to include (or wrap) different kinds of messages in a
oneof field of the message used in the streaming rpc.
For example,
service AbcService {
rpc StreamingCommunication(stream StreamMessage) returns (stream
StreamMessage) {}
}
message StreamMessage {
oneof message {
CreateAction create_action = 1
UpdateAction update_action = 2
...
}
}
