Real-Time Intelligence System for Event-Driven Data Analysis

Real-Time Intelligence System – Portfolio Project

Real-Time Intelligence System for Event-Driven Data Analysis

End-to-end streaming analytics platform built with Microsoft Fabric

Project Overview

I developed a comprehensive real-time data intelligence system using Microsoft Fabric’s Real-Time Intelligence capabilities to process streaming event data, perform advanced transformations, and deliver actionable insights through automated monitoring and interactive visualization.

Using a bicycle tracking dataset as the implementation case study, this system processes continuous streams of location-based telemetry data including vehicle identification, geographic coordinates, timestamps, and operational metadata. The solution demonstrates enterprise-grade streaming analytics with immediate insight extraction and decision-making capabilities.

Implementation Overview

Core Architecture

The solution implements a robust three-layer medallion architecture for data processing:

  • Bronze Layer: Raw data ingestion with minimal transformation, preserving original data for audit and reprocessing
  • Silver Layer: Cleaned and enriched data with parsed fields, calculated metrics, and business logic applied
  • Gold Layer: Optimized aggregations and materialized views for high-performance analytical queries

Key Components Implemented

1. Data Ingestion Pipeline

Configured real-time event stream from source to Eventhouse with automatic timestamp enrichment using SYSTEM.Timestamp() function for temporal context.

2. Automated Transformations

Implemented update policies with custom KQL functions to parse bike IDs, calculate capacity metrics, and generate operational recommendations automatically.

3. Real-Time Alerting

Deployed event-driven alerts monitoring bike availability with email notifications when inventory drops below critical thresholds (< 5 bikes).

4. Interactive Dashboards

Built multi-tile dashboards with column charts for availability trends and geographic maps for spatial analysis using latitude/longitude coordinates.

5. Anomaly Detection

Configured ML-based anomaly detection to identify irregular patterns in empty dock availability across multiple station locations.

6. Query Optimization

Created materialized views using arg_max() aggregation for instant access to current state data without full table scans.

Technical Challenges & Solutions

Challenge 1: Real-Time Data Transformation Without Manual Orchestration

Needed to automatically transform raw streaming data as it arrives, without building complex ETL pipelines or scheduling jobs.

Solution:

Implemented KQL update policies linked to stored functions. This enabled automatic, event-triggered transformations that execute milliseconds after data ingestion, maintaining a Bronze-Silver architecture pattern for data quality and lineage tracking.

Challenge 2: Efficient Current-State Queries on Streaming Data

Querying for the latest bike availability at each station required scanning millions of time-series records, causing performance bottlenecks.

Solution:

Created a materialized view using arg_max(Timestamp, No_Bikes) aggregation that maintains pre-computed current state. This reduced query execution time from seconds to milliseconds and enabled real-time dashboard refreshes.

Challenge 3: Cross-Platform Query Compatibility

Team members familiar with SQL needed to work with KQL-native systems without learning an entirely new query language immediately.

Solution:

Leveraged Fabric’s T-SQL integration for backward compatibility while using the ‘explain’ keyword to translate SQL queries to KQL. This provided a learning path and demonstrated KQL optimization opportunities.

Challenge 4: Proactive Monitoring at Stream Level

Required immediate notifications for critical inventory levels before data even reached the database layer.

Solution:

Configured event-driven alerts directly on the eventstream with field-level condition monitoring (No_Bikes < 5). This enabled sub-second alerting and email notifications for operational teams to respond to inventory issues immediately.
