gRPC Best Practice @ CoreOSFest 2017

Just small note for me. Hope the slide will be opened.

API design
- Idmpotency
  - It should be safe to retry an RPC without knowing whether it was processed
Example

	# th30z@u1310:[Desktop]$ psql -h localhost -p 55432
	# Password:
	# psql (9.1.10, server 0.0.0)
	# WARNING: psql version 9.1, server version 0.0.
	# Some psql features might not work.
	# Type "help" for help.
	#
	# th30z=> select foo;
	# a \| b
	# ---+---

	# The upstream server doesn't need a prefix! no need for wss:// or http:// because nginx will upgrade to http1.1 in the config below
	upstream yeomanserver {
	server localhost:3000;
	}


	server {
	listen 443;
	server_name legionofevil.org;
	root html;

	import json
	import socket

	s = socket.create_connection(("127.0.0.1", 5090))
	s.sendall(json.dumps(({"id": 1, "method": "Hello.Hello", "params": ["hello"]})))
	print s.recv(4096)

	import sys
	from gevent import server
	from gevent.baseserver import _tcp_listener
	from gevent.monkey import patch_all; patch_all()
	from multiprocessing import Process, current_process, cpu_count


	def note(format, *args):
	sys.stderr.write('[%s]\t%s\n' % (current_process().name, format%args))
