TCP over HTTP advantages

[Astimus]

Hi. I'm sorry for asking the question here.
What are the advantages of TCP over the HTTP ClickHouse interface? (performance, reliability, security, maintainability, support of different formats like parquet and arrow, streaming support)
As I understand, It is much harder to support Native format and interface because of lack of specification. Most likely, Apache Parquet+ HTTP does not lose in speed to the native interface.
Why have you decided to implement the library on the native interface? Thank you in advance.
