The new preview mode uses an in-browser query engine caching data locally, eliminating dependency on Spark sessions and reducing query load on source systems like Amazon Redshift. Users can preview transforms in about one second, accelerating iteration and development.

This upgrade supports various data formats and sources, including Parquet, CSV, JSON, and multiple databases. A toggle lets users switch between v2.0 preview and original Spark-based preview. While improving usability and performance, real-world scalability and compatibility depend on user environments.
