#Kafka to csv Pipeline

Call getData function to pull data into the Data folder.
It creates/updates three csvs and one file

• Recommendations to users
• mpg by users
• ratings by users
• File with current start kafka stream

It checks if the stream is in bad by checking if format of csv follows

• mpgStr = "GET /data/m/"
• rateStr = "GET /rate/"
• recStr = "recommendation request 17645-team14.isri.cmu.edu:8082, status 200, result:"

It also checks if the user id is [1,1000000] inclusive.

This function needs the port to be available
To connect to Kafka Broker Server with port forwarding by replacing
- [IP] with the ipaddress (Ex: 0.0.0.0)
- [port] with port number (Ex: 9092)
$ssh -o ServerAliveInterval=60 -L :localhost: tunnel@ -NTf

To kill connection at port after :
$lsof -ti:[port] | xargs kill -9

It needs Keys.py to have the correct information (substitute [topic] and [port] with the correct number):
TOPIC = "[topic]"
LOCAlPORT = "localhost:[port]"

Setup: it needs kafka-python, pytest, pytest-cov
$python -m pip install kafka-python
$python -m pip install pytest
$python -m pip install pytest-cov
