MySQL HeatWave Lakehouse

• MySQL HeatWave Lakehouse now supports enhanced functionality with the introduction of metadata columns and KEY partitioning. This update enables the storage of source information about file names in a special reserved column, _metadata_filename, and allows for more efficient data management through KEY partitioning. With this feature, you can create tables with partitioning definitions by using PARTITION BY KEY (partition_col), allowing you to improve data organization and querying capabilities. Additionally, generated column support is now complete for JSON and Delta tables. These enhancements expand the capabilities of MySQL HeatWave Lakehouse, providing you with more flexibility and control over your data.

  For more information, see Create Tables with Metadata Columns and Create Tables with Key Partitioning. (WL #17183, WL #17206)
