Readme.md

Please build a data pipeline that will:

• Read conversations data from clean-data.json
• Calculate the following metrics for each message:
  • word_count
  • tone - if the first word of the message has an odd number of letters, tone is negative, otherwise it's positive. Klaus' data scientists keep tweaking this algorithm to make it even more precise so this may change in the future.
• Calculate the following metrics for each conversation:
  • total_word_count
  • min_message_word_count
  • max_message_word_count
  • average_message_word_count
  • tone - the tone of the most messages in this conversation. If positive and negative messages are equal, set the conversation's tone to mixed
• Write the results into a file processed-data.json that has the same structure as the input file with the addition of the newly calculated fields.
• Anything that you can do to structure the pipeline in a way that makes it easier to add similar metrics in the future would be good.
• The starting point of an Apache Beam pipeline is provided but you can use any tool or framework you'd like.

Bonus:

• Create tests for the pipeline / the processing. Testing framework is up to you.
