Under the hood, gRPC will run your requests on the network threads, and an application provided Executor. (or a default, if you don't set one). However, waiting for the RPC to finish would still happen from the main thread. You can use the Future API if you would like a nice way of handling the response from a different thread. Note that RPCs will not time out if you don't provide a deadline. You can use stub.withDeadline() to set one.

It will automatically create and release connections as needed. Stubs should be safe to use by multiple places. > 1.
