Best way to insert list of entities in Spring JPA

Question

I have a list of entities. What is the best way to save it? Currently, I am using a for loop, which is taking a log of time:

List <Customer> cust:

for (Customer c: cust) {
 custRepository. save(c) 
}

I need to create list of customers almost 100+ at a time.... Which contains basic details if the customer.. Almost 5 cols only — Thomas, May 10 '18 at 14:51
**How your `custRepository` class looks like?** If it extends/implements `CrudRepository` then you should have `saveAll` method... — Jakub Ch., May 10 '18 at 15:00

You can use "batch Insert" for processing amount of data Example: using JDBC preparedStatement in a batch
