Release Notes

https://github.com/4paradigm/OpenMLDB/releases/tag/v0.8.5

OpenMLDB released a new version v0.8.5, including SQL syntax extensions, Iceberg data lake support, TTL type extensions, and improved user authentication functionality. The most noteworthy feature is the integration of the Iceberg engine and the enhancement of user authentication.

Iceberg is an open-source table format data lake management tool, focusing on providing a highly reliable, scalable data lake management solution. Its core features include atomic write mechanisms, multi-version data management, metadata management, etc., aiming to provide comprehensive data lake management functionality for enterprises. OpenMLDB integrates Iceberg into its platform, allowing users to directly read and write Iceberg data lakes while using OpenMLDB’s features. This results in higher data reliability and consistency, more flexible data operations and management, and more efficient data query performance, providing enterprises with a comprehensive and reliable data lake management solution.

OpenMLDB has also introduced user authentication functionality, allowing users to more flexibly manage and control database access permissions through SQL statements such as CREATE / ALTER / DROP USER. This feature not only ensures the security of the data but also enhances the convenience and flexibility of database management. Users can autonomously manage the creation, modification, and deletion of user accounts according to their actual needs, better meeting the enterprise's requirements for data access permission management, and improving the overall system's security and manageability.
