row's value in Windowing function
Key: HIVE-10142
URL: https://issues.apache.org/jira/browse/HIVE-10142
Project: Hive
Issue Type: New Feature
Components: PTF-Windowing
Affects Versions: 1.0.0
Reporter: Yi Zhang
For analytics with windowing function, the calculation formula sometimes needs
to perform over each row's value against current tow's value. The decay value
is a good example, such as sums of value with a decay function based on
difference of timestamp between each row and current row.
