30m Kevin Timoney Upgrade and rollback of database objects to work with required ONAP release |
Investigation of available technologies (liquibase and flyway) and why we chose our own solution.
Overview of how "policy-db-migrator" works - easy to use shell scripting solution which was easy to integrate with OOM.
"policy-db-migrator" features : Automatic version detection. Partial upgrade/downgrade in case of failure.
How implementing "policy-db-migrator" helped the project - benefits of pre-installed schema over JPA.
Looking forward - success in this area has led to us taking on other database related work - back up and restore, high availability and making control loop/policy framework database agnostic in the future to allow user to choose between mariadb and postgres.
