ASF GitHub Bot logged work on BEAM-8086: ---------------------------------------- Author: ASF GitHub Bot Created on: 23/Aug/19 22:01 Start Date: 23/Aug/19 22:01 Worklog Time Spent: 10m Work Description: amaliujia commented on pull request #9422: [BEAM-8086] add isRetraciton() to WindowedValue. URL: https://github.com/apache/beam/pull/9422 We need a way to mark WindowedValue as a retraction. Current idea is we should separate sub-classes of WindowedValue without and with retraction flag to reduce the impact of enabling retractions. It is mostly because I plan to use Boolean as the flag of retraction so each instance of WindowedValue will have 8 bytes overhead if we don't have such a separation. In the future, as the implementation of retraction work goes, I will probably add more sub-classes of WindowedValue which implements isRetraction(), and those will be used for retracting mode. ------------------------ Thank you for your contribution!
