Social Media Data Analysis using Vertex AI and Serverless Spark

Lab contributed by: TEKsystems

Overview

With the advent of cloud environments, the concept of huge capital investments in infrastructure in terms of capital and maintenance is a thing of the past. Even when it comes to provisioning infrastructure on cloud services, it can get tedious and cumbersome.

In this example, you will look at executing a simple PySpark code which runs on Serverless batch (a fully managed Dataproc cluster). It is similar to executing code on a Dataproc cluster without the need to initialize, deploy or manage the underlying infrastructure.

This repository processes tweets data using spark and finds out most popular trending #tags, plots a bar graph for the types of tweets and their followers count and also plots a map about the origin of the tweets.

Services Used

  • Google Cloud Storage
  • Google Cloud Dataproc
  • Google Cloud VertexAI

3. Permissions / IAM Roles required to run the lab

Following permissions / roles are required to execute the serverless batch

  • Viewer
  • Dataproc Editor
  • Service Account User
  • Storage Admin
  • Notebooks Runner

4. Checklist

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

1. GCP Prerequisites
2. Spark History Server Setup
3. Creating a GCS Bucket ad Uploading the Files
4. Creating a docker image

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

PROJECT_ID=                                         #Current GCP project where we are building our use case
REGION=                                             #GCP region where all our resources will be created
SUBNET=                                             #subnet which has private google access enabled
BQ_DATASET_NAME=                                    #BigQuery dataset where all the tables will be stored
BUCKET_CODE=                                        #GCP bucket where our code, data and model files will be stored
BUCKET_PHS=                                         #bucket where our application logs created in the history server will be stored
HISTORY_SERVER_NAME=                                #name of the history server which will store our application logs
UMSA_NAME=                                          #user managed service account required for the PySpark job executions
SERVICE_ACCOUNT=$UMSA_NAME@$PROJECT_ID.iam.gserviceaccount.com
CONTAINER_IMAGE=gcr.io/<<project-name>>/<<image-name>>:1.0.1 #Container Image needs to be provided
NAME=<your_name_here>                               #Your Unique Identifier
