Release Date:

  • Version 4.7.1 released on Apr 2026
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 Vector Table Data Type

In this version, the platform introduces a new data import type: VectorDB. A VectorDB data asset is a combination of structured and unstructured data. Users can now import this data type via a custom service. The platform stores unstructured data in the ‘content’ field, while structured data is stored in a columnar format, similar to internal tables.

Data Life Cycle

This service is designed to monitor and manage the end-to-end lifecycle of data assets (state, spark-internal, and vectorDB tables), covering Data Tiering and Retention processes. It offers Global-level management as a System Service. However, authorized users can opt to create their own service dependencies for Compaction and Retention instead of using the system default. The service is flexible enough to target a single specific asset or be scaled across multiple assets simultaneously.

Audit Log Menu

In this version, the Super Administrator role can view comprehensive activity and event logs directly through the Blendata Enterprise user interface. The Audit Log menu now provides detailed insights, including timestamp, user account, path, method, status/response codes, full request body, and error messages. Additionally, a ‘Download Result‘ button has been integrated for easier data retrieval.

Currently, the audit log tracks only activities performed via backend API calls.

Data Size Monitoring

We have enhanced the user interface to support storage path monitoring. Access to this menu and its data size information is restricted to Super Administrators. Additionally, users can now see overview information of storage path and export filtered results as a CSV file.

Available for internal file path, upload file method, and vectorDB asset.

Zeus Group Active/Standby Mode

In this version, we have introduced a new compute group mode: Active/Standby. This mode enhances fault tolerance by allowing users to designate one compute node as the default active and others as standby. If the active compute becomes unavailable, a standby compute automatically takes over to ensure uninterrupted job or process execution.
