The native execution engine is a groundbreaking enhancement for Apache Spark job executions in Microsoft Fabric. This vectorized engine optimizes the performance and efficiency of your Spark queries by running them directly on your lakehouse infrastructure. The engine's seamless integration means it requires no code modifications and avoids vendor lock-in. It supports Apache Spark APIs and is compatible with Runtime 1.2 (Spark 3.4), and works with both Parquet and Delta formats. Regardless of your data's location within OneLake, or if you access data via shortcuts, the native execution engine maximizes efficiency and performance
