The slide that goes with the workshop. - Demonstrate Transitioning to Real-Time Data Systems: This track shows how to transition from traditional batch processing to real-time data handling, emphasizing the critical importance of timely updates in scenarios like air traffic control where delays can be hazardous. - Implement Real-Time Data Solutions: Participants learn to implement and integrate a technology stack featuring Apache Spark, Cassandra, and PostgreSQL to effectively manage and process live data feeds from various sources, suitable for high-stakes environments. - Employ Streaming and Data Capture Technologies: The workshop demonstrates how to utilize streaming platforms and Change Data Capture (CDC) with tools like Redpanda and Debezium to ensure continuous data flow and immediate update capture, streamlining operations and data accuracy. - Apply Data Querying Techniques: It concludes by teaching how to apply advanced querying methods using Flink’s SQL client to incorporate real-time data queries into existing systems, ensuring efficient data manipulation and integration into relational and NoSQL databases.
