Use the Symphony Data Discovery Configuration Microservice to Maintain Application Properties

This applies to: Visual Data Discovery

You can use the Service Monitor to review and maintain the properties for each of the other Symphony microservices. It provides a centralized location where Symphony configuration properties can be maintained. However, it requires that the Symphony configuration microservice be configured and started first.

The Symphony configuration microservice is packaged with the Spring Cloud Configuration server, which allows Symphony to easily integrate with its Spring-based microservices and provides the mechanism by which Symphony property settings can be persisted in a supported PostgreSQL metastore or in a GitHub repository. The following diagram depicts this relationship.

After the Symphony configuration microservice is installed and started, the properties can be maintained on the Service Monitor's Properties tab.

If you have the configuration microservice configured and running in a high availability environment, you can maintain properties for microservices of a given type in a single location in the Service Monitor. For example, if you have two query engine microservices running in your high availability environment, you can change the properties for both microservices in a single location, ensuring that the query engine microservices operate in the same manner across the product nodes. A config-server-upload.jar utility is provided that can be used to migrate the microservice properties from your standalone Symphony servers to the Symphony configuration data in the high availability PostgreSQL data store, where the configuration microservice can maintain them. For more information see Migrate Properties to the Configuration Server.
