Implement historical record lookup and Slowly Changing Dimensions Type-2 using Apache Iceberg

This post will explore how to look up the history of records and tables using Apache Iceberg, focusing on Slowly Changing Dimensions (SCD) Type-2. This method creates new records for each data change while preserving old ones, thus maintaining a full history. By the end, you’ll understand how to use Apache Iceberg to manage historical records effectively on a typical CDC architecture.
