Can I read a section of yaml without spring ?
I have a yaml file with say 3 properties sections A,B,C .
I wanted to know if I can load a section only like B in in variable map of properties() .
Parse will do for whole yaml, and not sure on spring . Manual map feels troublesome

I need help to understand consumers without autowire in spring
It's in kotlin. I am beginner in kafka
I can read my kafka message very well with Autowired annotation but on trying to manually create I am getting 0 message .
Code description :
I call val prop=new Properties()
prop.put()
bootstrap server , key-value deserialiser ,schema url
create
consumer = new consumer(props)
then subscribe to topic and poll gives 0 count
but on autowire it gives count
Values are sent during test itself so,that can't be issue
I want to know if manual needs consumwr factory something

I want to understand the need of keys in JPA (beginner)
Hi , Jpa entity in java to me is an interface for Database operations for classes .
But , I don't understand need of defining primary key/foreign key in entities. It could be managed by database engines.
To me , it seems like Database is a Data at rest concept while Entity is a data in transit concept

Beginners doubt on JPA entity foreign mapping
Hi
I am new to jpa's and am learning of foreign key mappings between two table.
I need resources to learn on Jakarta JPA manytoone mappings.
I had a doubt on it , to me ,JPA seems like an inherited interface to database/sql operations,
so why does it matter if we implement foreign key mapping or not ,if it can be handled by Sql engines well ?
