How to persist session for a kie server


How to persist session for a kie server



I have been trying to understand if we can persist the state of a working memory in any Database?



I am creating a KIE server using a spring boot app as defined in the following example



https://github.com/kiegroup/droolsjbpm-integration/tree/master/kie-spring-boot



The KIE server is running, able to add containers to it and fire rules using the REST API.



What I fail to understand is can I save the working memory in the database and whenever the instance is down, I like to retrieve it back from DB.



I see from the examples there is a persistence.xml defined in the KJARS, is it for the same purpose? I tried adding the DB connection details but session information is not being saved in the table.



Also, can I scale it horizontally? Can I add more KIE servers and have a load balancer before?



Thank you!
