A new application is created by sending a POST request to the _applications resource:The request must include the application’s schema as an input entity in XML or JSON format. If the request is successful, a 200 OK response is returned with no message body.Because Doradus supports idempotent updates, using this command for an existing application is not an error and treated as a Modify Application command. If the identical schema is added twice, the second command is treated as a no-op.A new application is automatically created as an OLAP application if the Doradus server is appropriately configured. However, an application can be explicitly managed by the OLAP server by setting the application-level option StorageService to OLAPService.See The Email Sample Application section for an example schema in XML and JSON.
