I've just started learning Java Spring, and I'm looking to build an API that serves data scraped from a online marketplace using a python script. The problem is, I'm not entirely sure how to go about connecting the two. As far as I've been able to figure out, the python program should be able continuously run, and write the most recent market data to a database, which Spring can simply pull from. But how would I go about actually getting a python program(or even a normal, separate Java program) to run independently of the main API, while still being able to connect to the database?

I'm using IntelliJ as my IDE, and currently have these dependencies:
-Spring Boot DevTools
-Spring Web
-H2 Database
-Spring Data JPA

Any ideas, or extra resources would also be really appreciated
