We would like to create a metadata/masterdata management application. We are evaluating jmix for this reason. I would like to ask you if it is technically possible to create a jmixEntity in runtime, so that rest api, security and roles etc will be available to be used by this new entity.
Usage example: End user will import a table from the database, the table will be immediately available to list the contents and edit the data.
You can create arbitrary datasets in memory and show/edit them in standard UI components. However, such entities are not present in common metadata, so you cannot configure access control for them or request through the generic REST API endpoints.
