 Starting from v6.5.6 and v7.1.3, TiCDC Canal-JSON supports compatibility with the data format of the official Canal. When creating a changefeed, you can set `content-compatible=true` in `sink-uri` to enable this feature. In this mode, TiCDC outputs Canal-JSON format data that is compatible with the official Canal.
