I would like to have a shared feature between projects (i.e: one feature can be used at multiple projects).
Is it possible?
It is not possible to share single features across projects, however, it is possible to share the feature store of one project with another project.
For a detailed guide on how to do it, please see the documentation here.
To share a feature store with another project, share the dataset containing the feature groups and features ( projectname_featurestore.db ) as well as the dataset that contains the training datasets ( projectname_Training_Datasets ). To share datasets in Hopsworks simply right-click the feature store inside of your project dataset browser:
After you shared the datasets, you will have to accept them in the project that they were shared with. You should be able to see them in the dataset browser of the other project and accept them:
