How can I get the size of msg before grpc send it to client?

Like how many bytes it uses.

Assume you had a magic function that returned this value: how would you use
it?

Do you only care about the size of the message itself, or are you interested
in the amount of data gRPC will send over the network as well? (E.g.,
metadata, compression, framing data as well)

Are you using Protocol Buffers for your messages or something else?

Which language(s) are you programming in?

Hi Christopher,

Thanks for your reply!

I am thinking how to use this function to check if the msg is larger than the threshold of the channel we are using. and trying to avoid some resources exhaust issue.

I am using java and gprc 1.13.1 and protobuf 3.5.1.

I belive then that you want com.google.protobuf.MessageList.getSerializedSize() [1].

Correction: the interface is MessageLite, not MessageList.
