Ok.. it looks like you generate DDL automatically from a script . I wonder how can I optimize shema data type. For instance using Uint8 for age and Uint32 for index.
Just for sharing mine .. Note: clickhouse doesn't have concept of Foreign key or index. It is a column oriented database.

Hi, thank you so much for this! Have you had any experience running any OHDSI tools like the HADES stack https://ohdsi.github.io/Hades/ on clickhouse?
Hi,
it would be greate to have an omop shema for clickhouse. It is a column oriented sgbd very suitable for analytical
