--------------------------------
Summary: Split pure ValueFilter query with UDF to simplify and
accelerate valuefilter query
Key: IOTDB-3723
URL: https://issues.apache.org/jira/browse/IOTDB-3723
Project: Apache IoTDB
Issue Type: Task
Reporter: Yuan Tian
Assignee: liaolanyu
Now, query logics in TransformOperator and FilterOperator are too complex. It
is caused by some cases related to udf.
If we split pure ValueFilter query and expression calculaton with UDF, we can
simplify and accelerate valuefilter query.
And futhermore, we can use code gen to generate code to do the calculation more
effectively.
