Release Date: Nov 2025

Notebook Interpreter Version:
  • Python version 3.9 (The default version is 3.9, but the platform also supports version 3.8.x, 3.11.x, and version 3.12)
  • Spark version 3.5.3 (Support only 3.5.3)
  • Scala version 2.12 (Support only 2.12)

What’s New?

Support Tenant-Specific Datasource Configuration in Cerberus

Previously, Cerberus supported datasource configuration only at the global level, which applied the same settings to all tenants and limited the ability to tune performance for high-workload tenants.

In this release, Cerberus now supports tenant-specific datasource configurations, allowing each tenant to adjust connection-pool settings or increase max connections according to their workload.

This enhancement provides more accurate performance tuning and improved scalability in multi-tenant environments.

Enhanced User Experience by Remembering Your Latest Selections

Our platform has improved the user experience by remembering your latest selections, allowing you to continue working smoothly without reselecting filters or performing searches every time you refresh or switch menus.

This update applies to the following menus:

  • Data Catalog – The latest selected “Schema” is now remembered after refreshing or switching menus.
  • Notebook – The system now remembers your most recently selected “Zeppelin environment” after refreshing or switching menus.
  • Workflow Management – The latest value in the “Search Box”, “Latest Result” filter, and “Status” filter now remain after refreshing the page or switching between menus.

Enhanced Data Preview UI in the Simple Query Menu

Our platform has improved the UI for previewing query results after clicking “Estimate” in the “Simple Query” menu to enhance the user experience with loading progress indicators, export options, and job control through the Kill Query Job function.

Improved Readability with SQL Query Formatting

Our platform have improved function to format SQL code for better readability, supported in both “Data Exploration” and “SQL Editor” menus.
The system now adjusts line breaks and indentation automatically when using the “Format Query” button or keyboard shortcut.

  • Windows: Ctrl + Shift + F
  • Mac : ⌘ + Shift + F / Option + Shift + F

Able to specify a range of SQL commands to format, if no range is specified, the system will automatically format the entire SQL script.

Added “Latest Fired Time” Details to the Workflow Management Page and Workflow Details Section

Added a new “Latest Fired Time” field to display the last execution timestamp (e.g., 16-10-2025 – 12:00:00), helping users quickly identify when each workflow was last executed.

Set Default TBLPROPERTIES When Creating Delta Tables

Set default “TBLPROPERTIES” for Delta table creation based on the standard configuration when importing data or creating a table with the following default properties applied.

image

After creating or importing a new table, users can check the default configuration using
SHOW TBLPROPERTIES <schema_name>.<table_name>;

Added Support for Specifying Workspace in Parameters Using Path

Previously, users could specify only the notebook name when referencing a notebook in the parameter “notebookName”, and the system now supports both methods by specifying separate parameters using the combined path format (Workspace_Name/Notebook_Name), Both methods work in the same way.

Restricted Default Schema Access for Non–Super Admin Users

Our platform has restricted access to the Default Schema for general users to control the usage of resources within it. only users with the “Super_Admin” role are allowed to access the “Default Schema”, this update affects general users by disabling menus that are associated with the “Default Schema”.

For example, if a user has only one Default Schema, the Import Data menu will be disabled because that user no longer has permission to access the any Schemas.
