Write blog post of current technology stack of Waartaa

[rtnpro]

• proposed title: "Anatomy of Waartaa 0.1"
• Shortcomings of 0.1-rc-1
  • Not at all scalable
  • High resource utilization by app and mongodb
  • Too many read/writes to mongodb
• Solution
  • Upgrade to Meteor's OPLOG driver from 0.8 release (with support for complex queries)
  • Minimize writes to MongoDB:
    • write channel log once per server channel irrespective of the number of active waartaa users on the channel
    • minimize writes to add/remove a channel nick
    • Reduce storage complexity of logs. Storage complexity now depends on only the number of active channels and is irrespective of the number of active waartaa users.
• Async write to mongodb optimized app performance and brought down CPU usage
• The way ahead:
  • Run IRC server as a different service, and allow multiple instances of it for horizontal scaling.
  • Run multiple instance of waartaa's app server.
