---------------------------------
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.
