Tian Jiang reassigned IOTDB-460: -------------------------------- Assignee: Tian Jiang Resolution: Fixed > [Distributed] Remove data of outdated slots > ------------------------------------------- > > Key: IOTDB-460 > URL: https://issues.apache.org/jira/browse/IOTDB-460 > Project: Apache IoTDB > Issue Type: Improvement > Reporter: Tian Jiang > Assignee: Tian Jiang > Priority: Major > Labels: data-transfer, distributed > > In node addition/removal, the slots managed by a node will change. However, > the data of corresponding slots cannot be removed yet because the new holders > of the slots will pull such data to themselves. As the data pulling is issued > by the new holders randomly, it is hard for the previous holders to find out > when will the data be needless. As a result, the previous holder cannot > delete the local data with confidence. > It will be necessary to find a way for the previous holders to know when the > data has been replicated to the new holders so that they will be able to > remove the local data. -- This message was sent by Atlassian Jira (v8.3.4#803005)
