Is Spring batch in memory job repository good for production?

Question

Can you use in memory job repository in production if you are not looking for restarts of the job?

If yes, then does it have any impact on memory?

Answer 1

No. The in memory job repository is intended for test purposes only (it says it in the documentation here: http://docs.spring.io/spring-batch/trunk/apidocs/org/springframework/batch/core/repository/support/MapJobRepositoryFactoryBean.html). For production use, we recommend an in memory database such as HSQLDB.
