Channels
What problem does it solve?
History
How
- FIFO queue
- at-most-once delivery
- producer - channel - consumer
- network transparency
How is easy?
DEMOTIME
What else ?
- background tasks (instead of Celery, BUT!)
- send emails
- run expensive calculations
- image thumbnails
- etc..
- Zero-downtime deployment
- Extendability to other protocols or event sources (e.g. WebRTC, raw UDP, SMS)
- Optional low-level HTTP control on a per-URL basis
Does it scale?
I WANT IT BLAZINGLY FAST
Load testing
What's next
- improve Daphne
- more interface servers
- faster harder stronger
- official Django builtin
- write your own interface server, channel implementation
DEM SPEEDS - TEASER
