This repository represents a modular Azure Data Factory ingestion framework, where each module addresses a real-world data engineering scenario commonly found in enterprise data platforms.
This project showcases a production-grade Azure Data Engineering solution built using Azure Data Factory (ADF). Instead of focusing on a single pipeline, the project is designed as a collection of reusable ingestion patterns, reflecting how real enterprise data platforms are built and maintained.
Each module solves a specific data engineering problem such as incremental database loads, API ingestion, schema variability, monitoring, and CI/CD.
-
In real-world organizations:
-
Data comes from multiple source types (databases, APIs, files)
-
Each source has different ingestion challenges
-
Pipelines must be scalable, reusable, and easy to maintain
-
Monitoring and deployment are platform-level responsibilities
👉 This project is intentionally modular to demonstrate:
-
Pattern-based engineering
-
Platform thinking over one-off pipelines
-
How Data Engineers design enterprise-ready ingestion frameworks
🔹 Incremental SQL Data Load (Delta Strategy)
-
Scenario: Transactional databases where only new or updated records should be processed.
-
Timestamp-based watermark (last_updated)
-
Handles late-arriving / backdated data
-
Avoids full-table reloads
-
Cost-efficient and scalable design
🔹 REST API Ingestion with Dynamic Pagination
-
Scenario: Third-party APIs that return data in pages.
-
Range-based pagination
-
Automatically retrieves all available records
-
Scales without manual looping
-
API rate-limit aware design
🔹 Metadata-Driven File Ingestion
-
Scenario: Regular file drops from multiple teams or vendors.
-
Single dynamic dataset
-
Auto-discovery of files
-
ForEach + Switch-based routing
-
Eliminates pipeline and dataset sprawl
🔹 Dynamic Schema Mapping
-
Scenario: Multiple business entities with different schemas but identical ingestion flow.
-
Schema mappings passed as JSON parameters
-
Runtime schema selection
-
One pipeline supports multiple structures
-
Prevents schema-related pipeline failures
🔹 Monitoring & Failure Alerts
-
Scenario: Production pipelines requiring immediate operational visibility.
-
Azure Logic App integration
-
Automated email alerts
-
Captures pipeline context (run ID, table, pipeline name)
-
Covers silent and skipped failures
🔹 CI/CD with GitHub Integration
-
Scenario: Multiple engineers working on shared data pipelines.
-
Git-based version control
-
Feature branching & pull requests
-
ARM & YAML artifact generation
-
Safe deployments and rollback capability

| API Pagination | Scalably ingest third-party APIs | ADF, REST |
| Metadata-Driven Files | Multi-file ingestion | ADF, Params |
| Schema Mapping | Dynamic schema support | ADF, JSON Mappings |
| Monitoring | Alerts & operational readiness | ADF + Logic Apps |
| CI/CD | GitOps workflow | GitHub + ADF |
This project establishes a high-maturity Metadata-Driven Data Engineering Framework on Azure, transitioning from static ETL tasks to enterprise-grade orchestration. By decoupling logic from data and implementing a self-cleaning, event-driven architecture, the platform achieves:
-
Scalability & Reusability: Leveraged Parameterization and Dynamic Mapping to handle multi-entity ingestion (Customers, Drivers, Trips) through a single code path, minimizing technical debt.
-
Cost & Resource Optimization: Integrated Watermark Patterns for Incremental Loading (Delta Loads) and Logical Gating, ensuring Azure Consumption is limited only to changed datasets.
-
Operational Resilience: Implemented automated Data Validation, REST API Pagination logic, and Logic App Webhooks for real-time monitoring and proactive error alerting.
-
DataOps & CI/CD Excellence: Developed a robust Software Development Lifecycle (SDLC) using GitHub Version Control, Feature Branching, and automated ARM/YAML Template generation for seamless multi-environment deployment.
This framework represents a modern, Production-Ready approach to building sustainable, cost-effective, and Metadata-Driven data platforms in the cloud.
