This contains factual inaccuracies i believe, @Blargian to confirm

| The Kafka Engine does have some limitations: | ||
| - [Kafka message header](https://docs.confluent.io/platform/current/schema-registry/fundamentals/serdes-develop/index.html#wire-format) is not currently supported, so schema registry cannot be used | ||
| - Protobuf, ProtobufSingle are supported, while [ProtobufList](https://github.com/ClickHouse/ClickHouse/issues/78746) is not |

This is confusing, the link is with respect to INSERT commands not use in this table engine.

Thanks for the feedback Dale I've update the PR, please let me know if that looks ok Regarding ProtobufList and Schemas - I've spent quite some time digging into this, and even have an open source repo which replicates the issues, and allows you see what is and is not supported. ( To be honest, I wasted ~1-2 months of elapsed time trying to get ProtobufList to work, which is why I wanted to warn others NOT to waste their time. ) Repo: https://github.com/randomizedcoder/gdp If you have any issues running the example, please let me know. |

@genzgd is leading our protobuf efforts and is the resident expert here. We generally don't link to specific issues in the docs @randomizedcoder but i want @genzgd to review the doc and PR here. He can approve and discuss. |

Thanks. It would be great to understand more about the suggestion about "factual inaccuracies". Not sure what you are suggesting is inaccurate. |
|
Pretty disappointing |
