ClickHouse's MaterializeMySQL database now imports and retains all column comments from the source MySQL database.
Why it matters
This feature ensures that when users create a ClickHouse database using MaterializeMySQL, all column comments from the original MySQL schema are preserved. This helps maintain schema documentation consistency and improves clarity for users interacting with the materialized tables.How to use it
When using the experimental MaterializeMySQL feature to create a ClickHouse database, column comments from the MySQL source are automatically included without additional configuration.
