Yuan Tian created IOTDB-5715: -------------------------------- Summary: Improve the performance of query order by time desc Key: IOTDB-5715 URL: https://issues.apache.org/jira/browse/IOTDB-5715 Project: Apache IoTDB Issue Type: Improvement Components: Core/Query Reporter: Yuan Tian Assignee: Yuan Tian Fix For: 1.2.0 Attachments: data.zip
We found that order time desc is much slower than order by time asc. We can use the data in attachment and start a 1C1D IoTDB to replay that. ``` select * from root.sg1.d1 where s1 != 1 order by time asc; select * from root.sg1.d1 where s1 != 1 order by time desc; ``` -- This message was sent by Atlassian Jira (v8.20.10#820010)
