------------------------------
Summary: Optimize the underlying data classes to reduce
unnecessary memory overhead
Key: IOTDB-541
URL: https://issues.apache.org/jira/browse/IOTDB-541
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Engine
Reporter: DaweiLiu
The implementation of the current class holds all the primitive types that can
be used in the AggregateResult or Field classes, which means that if I were
just a boolean result, the requested memory would be more than 20 times the
amount of memory that needs to be used. This is very unfriendly for sensor-rich
scenarios, so one way to optimize is to to remove the extra fields and only
use the types we need
