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)

What’s New?

Ability to Delete Tags from the Tag List

Blendata now supports deleting tags directly from the platform. Users can remove unused tags easily by clicking the “X” icon, and a confirmation modal is displayed if the tag is currently in use.

Only users with the Super_Admin role can delete tags.

Separate Configuration for Upload Path and Internal File Path

Upload Path and Internal File Path can now be configured separately.
Previously, both paths were treated as the same location during file import. With this improvement, users can define each path independently, allowing more flexible configurations, especially when using wildcard patterns that should apply to only one specific path.

Workspace Git Merge

You can now compare two branches directly within the workspace to identify changed notes or files, automatically detect merge conflicts, and review or resolve them before merging.
This enhancement helps ensure that merged changes are consistent, conflict-free, and safely integrated into the main branch without unintentionally overwriting important updates.

Git Commit Id and Message

Added support for Commit ID and commit message to improve version tracking, traceability, and change management within the workspace.

Fixed Bug:

Import Data

  • BDEN-8502 Fixed an issue where default_schema could not be selected under Customized Config when importing multiple tables from a database via the Import Dataset and CDC (Internal Table) method.
  • BDEN-8588 Fixed an issue where the Overwrite option was incorrectly applied as Append when importing from internal file paths or Google Sheets, resulting in duplicate records.

  • BDEN-8454 Fixed an issue where saving as a view table in “SQL Editor” failed, even though the same CTE statement could be executed successfully.
  • BDEN-8455 Fixed an issue where saving as aggregate table in “SQL Editor” failed, even though the same statement could be executed successfully.

  • BDEN-8586 Fixed a UI layout issue where the “SQL Editor” page overflowed at a screen width of 1440px.
  • BDEN-8666 Fixed an issue where previewing data after setting conditions displayed incorrect results on the first attempt, requiring users to click “Preview” again in the “Simple Query” menu.

Notebook

  • BS1-59 Fixed an issue where switching the Realm while on the “Notebook” page did not refresh and still displayed the previous notebook.
  • BS1-63 Fixed an issue where the Environment dropdown list in Add Data Assets incorrectly displayed environments with the same Meta Store as the Zeppelin setting.
  • BS1-80 Fixed an issue where deleting a workspace on the Notebook page showed a success message, but the deletion was not actually applied.
  • BS1-91 Fixed a NullPointerException that occurred when notebook textbox values were empty or contained whitespace in a paragraph.
  • BS1-93 Fixed an issue where the Paragraph Display Mode (Simple/Report) was not applied correctly.
  • BS1-138 Fixed an issue where triggering a Notebook via Workflow in Scoped mode caused only a single interpreter instance to run. Resolved by executing the Notebook service type in Isolated mode when triggered from Workflow.

Service Management

  • BDEN-7981 Fixed an issue where setting isTrash = true in the “File Retention” job did not move files to Trash as expected.
  • BDEN-8336 Fixed an issue where running a “Table Update” job on a “Delta table” failed with the error “DELTA_ACTIVE_SPARK_SESSION_NOT_FOUND”.

  • BDEN-8436 Fixed a backend issue (WebFlux calls) where error details from Custom Service failures were not properly returned, resulting in missing error information on the UI and making it difficult for users to understand the issue.
  • BDEN-8532 Fixed UI text issues where the Service Name label and validation warning message were displayed incorrectly during service creation.

Workflow Management

  • BDEN-8279 Fixed an issue where schemas with the same name across different realms could not be deleted.
  • BDEN-8507 Fixed a UI alignment issue in the “User Management” menu where column headers were misaligned when assigning table permissions for data assets.
  • BDEN-8669 Fixed an issue where “Service Chain” permissions could not be shared in “User Management” menu.

  • BDEN-8662 Fixed a text alignment issue where dialog text was too close to the container border in the “Access Token Management” menu when performing actions.

Improvement:

  • BS1-34 Improved interpreter resource management for multiple running notebooks to prevent holding resources unnecessarily (e.g., in a 4-core interpreter where each notebook uses 1 core, queued notebooks can now utilize available resources instead of waiting only for the first running notebook to finish).
  • BS1-65 Improved z.importNotebook to support multi-level notebook import chains (e.g., NB #main → NB #1 → NB #2) without errors, allowing functions in nested notebooks to be called reliably.
  • BDEN-7994 Improved the “Create Aggregate Service” dialog by adding a “Query Data All Time Range” checkbox, allowing users to easily configure an all-time range in the UI.
  • BDEN-8184 Improved performance by introducing a cacheId (UUID) mechanism to reduce unnecessary permission data transfers, where the API now returns permission data only when the cacheId changes (e.g., permission update or cache clear), significantly reducing payload size and improving overall UI performance.
  • BDEN-8307 Improved the delete schema modal to clearly display schema details for both successful and failed deletion cases in the “Schema Management” menu.
  • BDEN-8350 Added a “Select All” option in the Partition Management list for easier handling of multiple partitions.
  • BDEN-8356 Added an “Execute Immediately” option for Alert Scheduler job in the “Service Management” menu.
