asyncio [https://docs.python.org/3.6/library/asyncio.html#module-asyncio] module and shares the same event loop (by default since Tornado 5.0). In general, libraries designed for use with asyncio [https://docs http1connection – HTTP/1.x client/server implementation • Asynchronous networking tornado.io loop — Main event loop tornado.iostream — Convenient wrappers for non-blocking sockets ☐ tornado.netutil — Miscellaneous very expensive. To minimize the cost of concurrent connections, Tornado uses a single-threaded event loop. This means that all application code should aim to be asynchronous and non-blocking because only

Conceptually, an event can be seen as a sentence, the event's type being the verb, the source the subject and the target the object. Event structure: { "eventType": event="">, "scope": event="">, "source": , "target": , "properties": } Source and target can be any Unomi applications using the JSON format and a typical page view event from a web site could look something like the following: Example page view event: { "eventType":

logically in it. For example, the send_private_message event would be in the /chat namespace, as well as the kick_ban event. Whereas the scan_files event would be in the /filesystem namespace. Each namespace the realm of a namespace or a Socket object, a dictionary that looks like: {"type": "event", "name": "launch_superhero", "args": ["Superman", 123, "km" need to send many packets on some long-polling transports. At this point, if you don’t know $ g_{event} $ , you probably will want to learn a bit more about it, since it is the base you will be working
