Core Data Preparation
- Data Preparation for JSON Lines (JSONL) Files: Users can add JSONL files to a project and structure the hierarchical data in row-column form. They can extract specific attributes from the hierarchy and can expand (or explode) arrays into rows in the worksheet.
Pivot and UnPivot: Users can pivot or unpivot columns in a worksheet to transpose/reshape the row and column data in a worksheet for advanced aggregation and analysis.
- Categorize and One-hot-encoding functions: Users can easily categorize similar values into fewer values to make analysis easier. With one-hot-encoding, the user can convert categorical values in a worksheet to numeric values suitable for machine learning algorithms.
- Column Browser with Quality Bar: A new panel for browsing columns is added to the left panel in the worksheet. This easy to use column browser interface allows users to show/hide columns, search for columns, highlight columns in the worksheet, etc. The panel also has a Quality bar that shows unique, duplicate and blank value count percentages within the column. The panel can also show any associated glossary terms.
- Project Level Graphical View: For a project with a large number of assets, the graphical view helps users understand the relationships between input data sources, sheets created, assets published, and Apache Zeppelin notebooks created. Users can navigate to the asset, notebook or the worksheet directly.
- Insert recipe step, add a filter to an existing step: Users can insert a new step at any location in the recipe. They can also add/modify existing filters for any recipe step.
- Data Type Inferencing optimization: Users can revert undesired inferencing done by data preparation engine and apply appropriate functions. They can revert or re-infer types as needed.
- Show where the data in a column comes from: The column overview in the bottom panel now has a Source property that shows if the column corresponds to a physical input source column, another worksheet or a step in the recipe. If the user hovers over a data source name, the application shows details of the formula when available and highlights the appropriate recipe step.
- UX Improvements in Filter-in-effect, Sampling, Join and Apply Rule panels: The user interface has been improved for clarity of icons and language used, visibility of information and button and better user flow for these panels. Users can also input constant values as inputs in the Apply Rule panel for text based user inputs.
Self-service and Collaboration
- Self-service scheduling: Data Analysts now have the ability to schedule import, publish and export activities. The Import/Publish/Export wizard offers the choice to perform the activity now, or to schedule it. For publish, a “snapshot” of recipes is saved for execution at the scheduled time. Users can continue to work on the project and modify recipes without affecting scheduled activity.
The “My Scheduled Activities” tab provides details of upcoming activities. The “Manage My Schedules” tab provides details of schedules and enables users to modify schedules.
Scheduled activities can be monitored on the My Activities page. Functionally it has the same effect as running the activity manually. All the schedules created in Enterprise Data Lake and activities scheduled in Enterprise Data Lake are also visible in the Administrator Console tool.
- Project History: Users (and IT/Governance staff) can view the important events that happened within a given project. These include events related to Project, Collaborators, Assets, Worksheets, Publications, Scheduled Publications, Notebook etc.
- Copy-Paste Recipe Steps: Users can copy specific steps or the whole recipe and paste into another sheet in the same project or another project. There is also a way to map the input columns used in the source sheet to the columns present in the target sheet. This enables reuse of each other’s or their own work in the creation of repetitive steps.
- Quick Filters for asset search in the data lake: In the search results, users have a single-click filter to get all the assets in the data lake that match the search criteria.
- Recommendation Card UX Improvements: The Recommendation cards in the Project view now show the reason an asset was recommended for inclusion in the project, and what action user should take.
- Details of Source Filters during Publish: During Publication, the Publish Wizard shows the details of "Source Filters" so the user understands the impact of including or not including the filters.
- Single Installer for Big Data Management, Enterprise Data Catalog and Enterprise Data Lake: The installation and upgrade flows have been improved and simplified with a single installer. Enterprise Data Lake customers can now install all three products in a single install. The total size of the single installer is just ~7GB due to better compression, as compared to the previous combined size of ~13GB. The process requires fewer domain restarts, and additional configurations can also be enabled in the same single flow.
- Blaze as Default Execution Engines for Enterprise Data Lake: All Enterprise Data Lake processes using Big Data Management mapping execution now use Blaze as the default engine. This has improved performance and consistency.
- SAML based SSO: Enterprise Data Lake now supports SAML based Single-Sign-On.
- Lake Resource Management UI: Administrators can manage the Enterprise Data Catalog resources that represent the external data sources and metadata repositories from which scanners extract metadata for use in the data lake. The Lake Resource Management page also verifies the validity of resources, the presence of at least one Hive resource, etc. so that Enterprise Data Lake functionality is usable. Changes done through the Lake Resource Management page do not require a service restart.
- Data Encryption for Data Preparation Service node: The temporary data created on Data Preparation Service nodes is encrypted for better security.
- Demo Version of IT Monitoring Dashboard: A dashboard created in Apache Zeppelin allows administrators to monitor Enterprise Data Lake user activities. The dashboard is not a product feature, but an example to show what is possible with the audit information. The dashboard is an Apache Zeppelin Notebook built on top of the Enterprise Data Lake user event auditing database. The Zeppelin Notebook and associated content are available on request, but it is unsupported. The Audit mechanism has been changed and improved now to support direct queries using JDBC.
- Performance Improvement in Import process using CLAIRE: Using the profiling metadata information available in CLAIRE, the import process optimizes the number of sub-processes created thereby improving the overall performance of Import
Enterprise Data Catalog (EDC)
- Enhanced Smart Discovery: By clustering similar columns from across data sources, EDC enables users to quickly associate business terms as well as classify data elements. Unsupervised clustering of similar columns is now based on names, unique values and patterns in addition to the existing data overlap similarity.
- Enhanced Unstructured Data Discovery (Tech Preview): Enhanced unstructured data support for accurate domain discovery using NLP and new file system connectivity.
- New Data Domain Rules: Override rules and new scan options for more granular control on rule based data domain inference.
- New Filesystems: Added support for cataloging of Sharepoint, Onedrive, Azure Data Lake Store(ADLS), Azure Blob and MapRFS
- New File Formats: Avro and Parquet support added in 10.2.1.
- Remote File Access Scanner: Mounting folders on Hadoop nodes not required for Linux and Windows filesystem, instead the new remote file access scanner uses SMB for Windows and SFTP for Linux for cataloging.
- Deep Dive Lineage support for BDM: End to End data lineage from Big Data Management with transformation logic and support for dynamic mappings
- Data Integration Hub: Users can now scan DIH to access metadata for all objects and its subscriptions and publications.
- Data Lineage from SQL Scripts(Tech Preview): End to End data lineage from hand coded SQL scripts to understand column level data flows and data transformations- includes support for Oracle PLSQL, DB2 PLSQL, Teradata BTEQ, HiveQL. Stored Procedures are not supported in this release.
- Qlikview: Scan reports and report lineage from Qlikview.
- User Experience Improvements

- SAML Support: For Single Sign-On.
- Multiple Business Term Linking: Allows custom attribute creation with Axon or BG term type to allow users to link multiple business terms with a single asset.
- Search Facet Reordering: Catalog Administrators can now reorder the default facet orders making business facets show up higher than the technical facets.
- New Missing Asset Link Report: To help users identify linked and unlinked data assets for a lineage-type source.
- Open and Extensible Platform
- New REST APIs for starting and monitoring scan jobs
- S@S Interop: Shared Infrastructure, Metadata Repository, Data Domain Definitions and Curation Results shared across EDC and S@S. Users can now scan a resource once to see it in both EDC and S@S.
