             Summary: Stage restore slices when in import phase already
                 Key: CASSSIDECAR-258
                 URL: https://issues.apache.org/jira/browse/CASSSIDECAR-258
             Project: Sidecar for Apache Cassandra
          Issue Type: Improvement
            Reporter: Yifan Cai
            Assignee: Yifan Cai


{color:#000000}In the coordinated write feature, when job consistency level is LOCAL_QUORUM or QUORUM, there is a chance that the slices are not staged in some nodes. Sidecar, then, errors out when processing such slice. The proposed solution is to allow staging such slices even if the restore job is in import phase already. The rationale is that when a restore job is marked as IMPORT_READY, the spark job has concluded that the staged slices in the current cluster already satisfy the consistency level. Staging and importing the additional slices are only going to improve the data consistency.{color}
