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.
