Retry the operation if the cluster in not available. Check the notes in `UserController` for additional info.\n\nTo run the example :\n- start a cluster (see the script `start-neo-cluster.sh` : it starts a cluster with docker)\n- run the spring boot application as usual","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnmervaillie%2Fsdnclustersample","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnmervaillie%2Fsdnclustersample","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnmervaillie%2Fsdnclustersample/lists"}
