The Streams

Wednesday, September 8, 2010

TM

What is Streaming?‣ Push delivery of tweets, as opposed to the REST (pull) API

‣ Implemented as HTTP long poll, aka the web page that never ends

‣ JSON (preferred) or XML content

Wednesday, September 8, 2010

TM

Streaming “Products”‣ hoses - slices of the entire tweet corpus‣ firehose‣ filter‣ sample‣ users - focused on specific users’ content‣ user streams‣ site streams

TM

Getting Started‣ cURL is your friend

‣ twurl is an even better friend

‣ Many libraries available

Wednesday, September 8, 2010

TM

User Streams‣ Goals

‣ Support single-user connections (e.g. desktop applications)

‣ Reduce dependency on polling

‣ Provide a true real time experience to users

Wednesday, September 8, 2010

TM

Data Delivered‣ All data is delivered as a JSON message on a single line

‣ First message - your friends

‣ Statuses

‣ Direct Messages

‣ Events

Wednesday, September 8, 2010

TM

‣ Events represent user activities that are not message delivery

‣ This includes

‣ favorites

‣ follows

‣ profile updates

What are Events?

Wednesday, September 8, 2010

TM

‣ event - indicates the type of event

‣ source - the user who initiated the action

‣ target - the user who owns the affected object.

‣ target_object (optional) - the affected object

‣ created_at - the time this happened

Event Schema

TM

Site Streams‣ Goals

‣ Like User Streams

‣ But for “services”, not desktop apps.

‣ Multiplex many users’ events onto a single connection

Wednesday, September 8, 2010

TM

Data Delivered‣ Just the same as user stream

‣ But every message is wrapped with a “for_user” tag, which gives the ID of the user to whom this message applies

Wednesday, September 8, 2010

TM

Keys to Success‣ Use OAuth

‣ Use JSON

‣ Process messages asynchronously

‣ Make sure you have adequate bandwidth

‣ Be prepared for additional message types
