Social Network with Serverless Spark and GraphFrames

1. Overview

In this use case, we will use Graphframes with Serverless Spark to build a network of users based on the characters present in the GOT books.


2. Services Used

  • Google Cloud Dataproc
  • Google Cloud Storage
  • Google BigQuery

3. Permissions / IAM Roles required to run the lab

Following permissions / roles are required to execute the serverless batch

  • Viewer
  • Dataproc Editor
  • BigQuery Data Editor
  • Service Account User
  • Storage Admin

4. Checklist

To perform the lab, below are the list of activities to perform.

1. GCP Prerequisites
2. Spark History Server Setup
3. Uploading scripts and datasets to GCP
4. Creating a BigQuery Dataset

Note down the values for below variables to get started with the lab:
