correct way to shut down a synchronous server

[Jeff]

Hi all,

Is there an example of the correct way to shut down a synchronous server? or do synchronous servers not need to be explicitly shutdown? Thanks!

You can call a grpc::Server::Shutdown with a timeout, after the timeout the pending rpcs will be cancelled. In your rpc handler (if you have long-lived streaming or rpcs), you will need to check ServerContext::isCancelled to finish up the rpcs. The sync server will not finish cleanup before you finish all the rpcs.
