Hello @wk989898, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

Hello! Gemini or gemini-code-assist here, providing a summary of this pull request. Based on the title [DNM]: test rename table in debezium and the minimal changes, this PR appears to be a work-in-progress or a specific test case setup. The primary intent seems to be adding or verifying the handling of the RENAME TABLE DDL statement within the Debezium integration tests. The change itself is a single line added to a SQL script used by these tests.

Highlights

• Debezium Integration Test: This PR modifies a SQL script used in the Debezium integration tests.
• RENAME TABLE DDL Test: A specific RENAME TABLE statement is added to the test script, likely to test how Debezium handles renaming a table back to its original name or a different schema/name combination.

Changelog

• tests/integration_tests/debezium/sql/ddl.sql
  • Added a RENAME TABLE statement (RENAME TABLE rename_t8 TO test.t8;) at line 148 to the DDL test script.

Code Review

This pull request, currently marked as "Do Not Merge" (DNM), adds a test case to tests/integration_tests/debezium/sql/ddl.sql. The change introduces a RENAME TABLE statement that renames a table to a fully qualified name (e.g., database.table).

This is a good addition as it enhances test coverage for DDL handling, specifically for RENAME TABLE operations where the target table name includes the schema/database qualifier. The change is clear, concise, and fits well within the existing test structure.

If this PR were to be prepared for merging (i.e., the DNM prefix removed), please ensure the pull request description, checklist, and release note sections are thoroughly completed as per the template.

Merge Readiness

As this pull request is marked "[DNM]" (Do Not Merge), it is understood to be a work in progress or for testing purposes and is not currently intended for merging.

Should this PR be considered for merging in the future, the following would be required:

• Removal of the "[DNM]" prefix from the title.
• A complete and accurate pull request description, including the problem solved and the changes made.
• Filling out the checklist, including test details.
• Providing an appropriate release note if applicable, or stating None.

The code change itself is minor and appears correct for its testing purpose. I am unable to approve pull requests; please ensure further review and approval by authorized maintainers before any merge.
