This is a modified version of programs based on an article "Getting started with Apache Kafka in Python"

In producer-raw-recipies.py, it uses requests to get recipes from allrecipes.com and stores to topic raw_recipes.

In producer_consumer_parse_recipes.py, it consume the message from raw_recipes and parse the recipes then stores into another topic parsed_recipes.

In consumer-notification.py, it consume the parsed recipes and print out an alerts if the calories of a recipe is greater than 200.

To run the program you need a stand alone Zookeeper and Kafka. Please refer to the article "Getting started with Apache Kafka in Python" for more info.
