In order to meet the cooperative management between different replicas, the FE selects one of several replicas as the upload node, while the replica that is not selected will only check whether the current segment data has been uploaded on the cluster, and synchronously delete the local data. The copy of the selected upload file will upload the data file normally, and upload the data of the current tablet to the cluster for other fragment checks.
