Support for Tuple and Nested Structures in Cap'n'Proto Format

Why it matters

This feature enables ClickHouse to directly interpret and query complex data types like tuples and nested structs encoded in the Cap'n'Proto serialization format. It solves the problem of limited format compatibility, allowing users to seamlessly integrate Cap'n'Proto data with nested structures into ClickHouse, enhancing interoperability and data processing capabilities.

How to use it

Users can read Cap'n'Proto formatted data containing Tuple and Nested structures by specifying the appropriate input format settings when importing or querying data. Ensure that the data schema corresponds to the expected nested and tuple types in ClickHouse, enabling direct parsing without additional transformation steps.
