Yifu Zhou reassigned IOTDB-1183: -------------------------------- Assignee: Yifu Zhou > Optimize Query Performance in Cluster > ------------------------------------- > > Key: IOTDB-1183 > URL: https://issues.apache.org/jira/browse/IOTDB-1183 > Project: Apache IoTDB > Issue Type: Improvement > Components: Cluster > Reporter: Yifu Zhou > Assignee: Yifu Zhou > Priority: Major > Fix For: 0.12.0 > > > In IoTDB cluster version, query performance is not good enough, especially if > we need to read the data from remote nodes. We need to reduce unnecessary > operations and improve the query performance in cluster version ASAP. > 1. ManagedSeriesReader will sync leader for each timeseries. For example, if > query select s_1,s_2 from root.to.path where time < 5, it will do > syncLeaderWithConsistencyCheck twice. Actually it only need to do check once > for each query. I will fix it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
