Spring-Batch without persisting metadata to database?

by

Simply create a configuration without datasource for Batch configuration :

@Configuration
@EnableAutoConfiguration
@EnableBatchProcessing
public class BatchConfiguration extends DefaultBatchConfigurer {

    @Override
    public void setDataSource(DataSource dataSource) {
        // override to do not set datasource even if a datasource exist.
        // initialize will use a Map based JobRepository (instead of database)
    }

}

It will initialize JobRepository and JobExplorer with a in memory map based implementation.

and you can use you’re production datasource as well even if auto configured with spring boot.
