HikariCP question
I set the spring.datasource.hikari.maximum-pool-size=30 but it defaults to 10. It works fine locally but not when application is deployed which is odd. Any debugging tips here on why it defaults to 10 instead of overriding this to the value I set?

Access denied for DB user in Spring Boot tests
I am trying to perform integration tests with Spring Boot, JUnit, and Mockito. When I run the tests, I get a bunch of exceptions, but it frequently mentions:
Access denied for user 'latte_test'@'localhost' (using password: YES) or similar. In application-test.yml, I have set the database credentials as environment variables. In IntelliJ IDEA Community, I have set their correct values in each test execution configuration (Run > Edit configurations for the test class and its @Test method). In MariaDB, I have granted the necessary permissions to the user for the database in question. Outside of the tests (in the main package), everything works correctly; it connects to the database by setting the values of the environment variables in Run > Edit configurations.

The problem comes from the fact that I can't seem to find any way to do a union and include pagination in the select.
What I want is something along the lines of the following SQL
```

Do You Manually Write Filtering/Sorting for Each API or Use a Generic Solution?
In most applications (99.9% of them), we typically have a listing API for resources that supports filtering, sorting, and searching.
From what Iβve seen, developers usually write custom query logic or conditions for each of these operations manually, per resource.
However, I find this to be repetitive and somewhat labor-intensive across multiple projects....
