1. MONGREL 2 Will Speak
2. A STORY or how Mongrel 2 came to be
3. RAGEL in the beginning there was the state machine compiler
4. RAGEL STATE MACHINE COMPILER ⇒ Compiles state machines into code
5. tokenising, regex & parser combines
6. fast and efficient parsing
7. MONGREL then came a
8. Ruby webserver Rock solid HTTP parser Easily scalable
9. ØMQ along came a whole lot of nothing
10. Provides a brokerless messaging architecture where clients and servers communicate via a Berkeley Sockets style interface “
11. a standard socket looks just like
12. a standard socket far more than
13. MONGREL 2 Add them all together and you get
14. fast and efficient parsing tried and tested HTTP support brokerless scalability from Mongrel Ragel ZeroMQ
15. fast and efficient parsing tried and tested HTTP support brokerless scalability from Mongrel Ragel ZeroMQ
16. fast and efficient parsing tried and tested HTTP support brokerless scalability from Mongrel Ragel ZeroMQ
17. synchronous http requests offloads
18. persistent state async protocols &
19. A PROTOCOL or what Mongrel 2 can do for us
20. REQUEST/RESPONSE a millisecond in the life of a mongre2 request
22. Request 1 Server IIS-01 Headers { “method”: “post”, … } Path /LockedQueueNoSql Body { “name”: “willspeak”, “affiliates”: [ …. ]}
23. Request 1 Server IIS-01 Headers { “method”: “post”, … } Path /LockedQueueNoSql Body { “name”: “willspeak”, “affiliates”: [ …. ]}
24. Request 1 Server IIS-01 Response [ { … }, { … }, …. ]
25. Request 1 Server IIS-01 Response [ { … }, { … }, …. ]
31. NETSTRINGS simple data serialisation
32. 12:hello world!, prefixed by length data encoded as UTF-8 assemble the delimiter committee
33. PACKETS inside the envelope
34. 12:hello world!, prefixed by length data encoded as UTF-8 assemble the delimiter committee
35. REQUEST PACKET FORMAT IIS-01 1 hello/world 2:{},4:body, webserver id requested path numeric request id netstring encoded json request headers netstring encoded request body
36. RESPONSE PACKET FORMAT IIS-01 1:1, hello Mongrel2 webserver id response data space-separated netstring of response ids
37. DEMO what you’ve all been waiting for
