Contributions summary:Serhii's commits focus on splitting and restructuring options related to GraphDB within the Gentics Mesh open-source headless CMS. They are modifying Java configuration files, specifically within the `AbstractMeshOptions.java` and `MeshOptions.java` files, to separate GraphDB-related configurations. This likely involves refactoring the configuration for the underlying database used by the CMS, enabling better maintainability and flexibility in managing database-specific settings.
