Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

• Producers send messages to brokers
• Consumers read messages from brokers
• Messages are sent to a topic

Sinatra like routes in Rails controllers

A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.

jwo

class Api::RegistrationsController < Api::BaseController
  
  respond_to :json
  def create

    user = User.new(params[:user])
    if user.save
      render :json=> user.as_json(:auth_token=>user.authentication_token, :email=>user.email), :status=>201
      return
    else

# coding: utf-8
#
# Encode any codepoint outside the ASCII printable range to an HTML character
# reference (https://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Character_reference_overview).
def encode(string)
  string.each_codepoint.inject("") do |buffer, cp|
    cp = "&#x#{cp.to_s(16)};" unless cp >= 0x20 && cp <= 0x7E
    buffer << cp
  end
end
