About This Architecture

AWS Data Pipeline using DMS to EMR Analytics demonstrates a modern data integration architecture that ingests heterogeneous source databases (MySQL, MSSQL) via AWS Database Migration Service into S3 raw storage. EMR Cluster processes this data, writing optimized Hudi-formatted tables back to S3 while simultaneously populating RDS (Postgres) and DynamoDB for operational queries. Athena enables SQL analytics directly on Hudi data in S3, eliminating the need for separate data warehouses. This pattern solves the challenge of consolidating multi-source databases into a unified, cost-effective analytics platform while maintaining both batch and real-time query capabilities.

How do I build an AWS data pipeline that ingests multiple databases and enables analytics with EMR and Athena?

This diagram shows a complete AWS data pipeline: AWS DMS migrates data from MySQL and MSSQL into S3 raw storage, EMR Cluster transforms and processes this data into Hudi-optimized tables, and Athena queries the results directly from S3. The pipeline also populates RDS (Postgres) and DynamoDB for operational use cases, creating a unified analytics platform.
