The following features have been added, improved, or updated for this Oracle Big Data Discovery release.
Transform-related features
This release includes these transform-related features and improvements:
- You can switch between row view and value list view in Transform. You can toggle the Transform data grid view in Studio, to examine attributes in the project data set. The data grid can display either a row view — a list of records from the project data sample, where each row represents a record, or a value list view of attribute values. This view shows attribute value distribution in a column display. It lists unique attribute values found in the data sample, listed in descending order by frequency.
- Improved performance of previews in Transform.
Improvements in data scale and management
This release includes these improvements to data and scale management:
- Improved performance of join operations.
- Improved performance of Geotagger lookups. The Geotagger model has been updated to improve its performance. When you update the Geotagger model, you obtain a new database of geonames. For information on how to update the database with geonames, see The Data Processing Guide.
Data science capabilities
This release includes these changes that make data science tasks easier for all users in BDD:
- Improved Studio chart component provides a consistent user experience.
- The type in Studio has an additional advanced visualization type, the Scatterplot Matrix. The matrix plots three or more metrics against each other and shows a binned scatterplot and correlation value for each pairing, so that you can visually review the relationships between attributes. For information on using and configuring a Scatterplot Matrix, see the Studio User's Guide.
