I‘m trying to use dataManager to save 90000 entities without relation entity and it cost about 660 seconds insert into database.So is there any config or method to help me save large size of entity more quickly?
I guess you were not using eclipselink batch writing.
You can add below to your project and try again.
eclipselink.jdbc.batch-writing = jdbc
eclipselink.jdbc.batch-writing.size = 1000
