This command line application parses a stream of events and produces an aggregated output.

Aggregated output contains, for every minute, a moving average of the translation delivery time for the last X minutes.

• Clone this repository git clone https://github.com/noraiz-anwar/backend-engineering-challenge.git
• Go to folder cd backend-engineering-challenge
• run [python 3] unbabel_cli.py --input_file [path to .json file] --window_size [number of minutes] [filter arguments]

events.json is in same directory as unbabel_cli.py in these examples.

• python3 unbabel_cli.py --input_file events.json --window_size 10
• python3 unbabel_cli.py --input_file events.json --window_size 10 --client_name booking
• python3 unbabel_cli.py --input_file events.json --window_size 10 --client_name easyjet --source_language en
• python3 unbabel_cli.py (defaults: input_file=events.json and window_size=10)

Running average can also be calculated based on any valid key:value filtering of events.

For example:

• python3 unbabel_cli.py --input_file events.json --window_size 10 --client_name booking

Calculates, for every minute, running average for last 10 minutes of events for "booking" client.

unbabel_cli considers that:

• Events in input file are sorted in ascending order of time.
• App was tested on Python 3.6.0
