Tian Jiang created IOTDB-2296: --------------------------------- Summary: Support list in queries Key: IOTDB-2296 URL: https://issues.apache.org/jira/browse/IOTDB-2296 Project: Apache IoTDB Issue Type: Improvement Components: Core/Query Reporter: Tian Jiang
Queries like SHOW TIMESERIES (or DEVICE) and COUNT TIMESERIES only accept one path as its argument, which may introduce inconvenience if the desired query is "SHOW DEVICE root.sg1,root.sg2". Moreover, in the distributed version, queries are often split into subqueries and routed to different nodes, if query plans do not support lists of paths, a node may have to be queried many times to get results. So we should support lists in such queries. The modification should be made both to the grammar definition and plan structure. -- This message was sent by Atlassian Jira (v8.20.1#820001)
