Project mention: Let's write a simple microservice in Clojure | dev.to | 2024-04-26

This involves initializing a HikariCP connection pool and Flyway for database migrations. The logs confirm that the database schema validation and migration checks were successful. The startup of the Jetty HTTP server follows, and the server becomes operational and ready to accept requests on the specified port.

> 2. ORMs do not hide SQL nastiness.
This is certainly true!
I mean: ORMs are now well known to "make the easy queries slightly more easy, while making intermediate queries really hard and complex queries impossible".
I think the are of ORMs is over. It simply did not deliver.
If a book on SQL is --say-- 100 pages, a book on Hibernate is 400 pages. So much to learn just to make the easy queries slightly easier to type? Just not worth it.
I prefer jooq any day over ORMs. And dont get me started over what tools like Hasuna have to offer.
There are also some languages (forgot the names) that are SQL-done-right. Select in the back, more type safe, more logic, more in the same steps as the query gets executed. These need to be adopted by PG and MySQL and we're good to go. (IMHO)
