描述

Feature request

Which Delta project/connector is this regarding?

  • Spark

  • Kernel
  • Other (fill in here)

Overview

Clustered tables support columns with stats collected on them, so generated column should work. We should add testing to cover this scenario.

Further details

We can add tests for generated columns in ClusteredTableDDLSuite.scala

研究方向
Review ClusteredTableDDLSuite.scala in the delta repository. Add test cases that verify generated columns work with clustering, including scenarios where generated columns are used as clustering keys. Refer to existing tests in the same suite for patterns. Ensure the tests cover both creation and querying of clustered tables with generated columns.
