Zhihao Shen created IOTDB-6244:
----------------------------------
Summary: Add new statistical aggreators include stddev and
variance.
Key: IOTDB-6244
URL: https://issues.apache.org/jira/browse/IOTDB-6244
Project: Apache IoTDB
Issue Type: New Feature
Components: Core/Query
Reporter: Zhihao Shen
Assignee: Zhihao Shen
Fix For: 1.3.1
Many databases like MySQL, PostgreSQL, Trino and Doris have already support
built-in statistical aggreators like stddev and variance, while currently IoTDB
has not. Hence we decide to write similar aggreators to extends IoTDB's
aggression functionality.
