Hello @ti-chi-bot, 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
As gemini-code-assist, I've reviewed this pull request. The primary goal is to add a new documentation page detailing the data replication capabilities of TiCDC. This PR, which is an automated cherry-pick from a Chinese documentation repository, introduces the new document and updates the table of contents and the TiCDC overview page to link to it.
Highlights
- New Documentation Page: A new document,
ticdc/ticdc-data-replication-capabilities.md, has been added. It covers how TiCDC works, supported downstream systems, the scope of replicated data (supported/unsupported DDL/DML), and limitations. - Table of Contents Update: The
TOC.mdfile has been updated to include a new "Reference" section under the TiCDC documentation, adding a link to the new capabilities document along with many other existing TiCDC reference links. - Overview Page Link: The
ticdc/ticdc-overview.mdfile has been modified to include a link to the new data replication capabilities document in its introductory paragraph.
Changelog
- TOC.md
- Added a new 'Reference' section under TiCDC documentation.
- Included a link to the new data replication capabilities document.
- Added links to numerous other existing TiCDC reference documents.
- ticdc/ticdc-data-replication-capabilities.md
- New file added.
- Contains detailed information on TiCDC's data replication capabilities, including how it works, supported downstreams, replication scope, and limitations.
- ticdc/ticdc-overview.md
- Added a link to the new 'TiCDC Data Replication Capabilities' document in the introduction.

Code Review
This pull request introduces a new document, ticdc-data-replication-capabilities.md, detailing TiCDC's replication capabilities, and updates the Table of Contents and the TiCDC overview page to include links to this new document. The new content is generally clear and informative.
However, there are critical merge conflict markers in TOC.md and ticdc/ticdc-overview.md that must be resolved before merging. Additionally, the new documentation file has a few minor stylistic and formatting issues that could be improved for consistency and readability.
I've reviewed the changes based on the provided style guide, focusing on clarity, technical accuracy, formatting, and adherence to Markdown best practices.
Summary of Findings
- Merge Conflict Markers: Files
TOC.mdandticdc/ticdc-overview.mdcontain merge conflict markers (e.g.,<<<<<<< HEAD,=======,>>>>>>> ...). These are critical issues that will break the documentation and must be resolved. - Markdown Formatting: In
ticdc/ticdc-data-replication-capabilities.md, there are minor formatting issues such as non-standard list markers (+instead of-or*), a missing space, a zero-width space in a heading, and a missing newline at the end of the file. Addressing these will improve consistency and readability. - Style Guide Adherence: The review considered elements from the style guide, including writing in the second person, using present tense, consistent terminology, sentence case for headings, proper use of backticks, and Markdown formatting best practices. The new document generally adheres well, with minor areas for improvement noted.
Merge Readiness
This pull request adds valuable documentation on TiCDC's data replication capabilities. However, it cannot be merged in its current state due to critical merge conflict markers in TOC.md and ticdc/ticdc-overview.md. These must be resolved first. There are also some minor stylistic suggestions for the new ticdc-data-replication-capabilities.md file that would enhance its quality.
Once the critical issues are addressed, this PR will be in much better shape. As a reviewer, I am not authorized to approve pull requests, so please ensure these changes are made and then seek further review and approval from the maintainers.

It looks like there's a missing space between 'statements' and '(excluding system tables)'. Adding a space would improve readability. 1

There was a problem hiding this comment.
There seems to be a zero-width space character (U+200B) at the end of the heading 'Limitations'. This character is invisible but can sometimes cause rendering or processing issues. It's best to remove it. 1
