Pull Request Overview

This PR fixes a bug related to importing tables with changefeed where partitioning settings are not properly applied when the primary key type is not Uint32 or Uint64. The fix ensures that changefeed partitioning configuration is only applied for tables with supported primary key types.

• Added logic to check the primary key type before applying partitioning settings in changefeed creation
• Enhanced test coverage to verify proper behavior for different primary key types
• Added new test helper functions to validate topic partitioning settings
