How do I dynamically populate a list with data from a JSON file at regular intervals in Spring boot.
I'm thinking it can be done using @Schedule.
Task: To create an api which performs some computations on data received from a json file and dynamically change the output as new data adds.
I've been able to create an api which takes in a POST request from Postman which in turn populates my List and performs the computation, but i need to automate this process using a file, which will dynamically get new data.
But could someone please highlight the exact procedure to do this.

As @Scheduled is an asynchronous operation it won't produce output for rest response.
Here could be following ways to process JSON file.
- You can define an endpoint to submit JSON file.
- Do computations and store in DB and then return the response immediately. But in case JSON file processing takes a long time then you should do computations in a background thread and return "In Progress" response to the user.
- Define a separate API for fetching the list of data collected through JSON.
