MySQL is a widely used open-source relational database management system (RDBMS) that provides a robust platform for storing and managing structured data. In a streaming ETL (Extract, Transform, Load) workflow, MySQL often serves as a destination for transformed data, enabling real-time data storage and query execution. Its scalability and flexibility make it a core component for applications requiring structured, relational data processing.

• Real-Time Data Storage: Load transformed streaming data into MySQL for structured and reliable storage.
• Transactional Data Analysis: Use MySQL to store transactional data for real-time reporting and analytics.
• Integration with Applications: Feed ETL-transformed data into MySQL to support application backends with fresh and consistent datasets.
• Cross-Dataset Joins: Store data from multiple ETL sources in MySQL to enable complex relational queries and aggregations.
