Clickstream Analytics Dashboard with StarTree Cloud Free Tier and Streamlit

This guide will walk you through creating a real-time clickstream analytics dashboard using StarTree Cloud Free Tier (Apache Pinot) and Streamlit.

Use Case

An e-commerce company wants to understand user behavior on their website to improve engagement, streamline the customer journey, and increase conversions. They need real-time insights into how users interact with their website's content and design.

Solution

Use the following technologies:

Apache Pinot: A real-time OLAP datastore to capture and analyze clickstream data.
StarTree Cloud Free Tier: A managed service for Apache Pinot, providing a free tier for experimentation and development.
Streamlit: A Python framework for building interactive web applications, perfect for creating our dashboard.

Dashboard Features

The dashboard will provide the following insights:

Event Counts by Type: A bar chart showing how often different user actions occur (e.g., page views, product clicks, add to carts, purchases).
Average Duration by Event Type: A table displaying the average time users spend on each type of event.

Benefits

Content Optimization: Identify underperforming pages and improve them based on user engagement.
Conversion Funnel Enhancement: Analyze the user journey and find areas where users drop off.
Personalization: Tailor website content and recommendations in real-time.
A/B Testing: Measure the impact of website changes by comparing clickstream data.
Marketing Campaign Effectiveness: Track the success of marketing campaigns.

Code

[streamlit_app.py] For the StarTree Free Tier - Serverless use the following script

Note: Before running the script make sure to update the Pinot Broker URL and Bearer Token

import streamlit as st
   import requests
   import pandas as pd
   import altair as alt
   # StarTree Cloud Broker URL and Bearer Auth Token
   PINOT_BROKER_URL = 'https://broker.pinot.XXXX:443/query/sql'  # Ensure the URL ends with /query/sql

    st.json(headers)  # Log headers to ensure they are correctly formatted
    response = requests.post(
        PINOT_BROKER_URL,
        json={'sql': query},
        headers=headers

    if response.status_code != 200:
        st.error(f"Error querying Pinot: {response.status_code}{response.reason}")
        st.text(response.text)  # Display the response text for additional debugging
