mxm opened a new pull request #12531: URL: https://github.com/apache/beam/pull/12531
By default, the Python SDK adds a timer output timestamp equal to the current
timestamp of an element. This is problematic because:
1. We hold back the output watermark on the current element's timestamp for
every timer
2. It doesn't match the behavior in the Java SDK which defaults to using the
fire timestamp as the timer output timestamp (and adds a hold on it)
3. There is no way for the user to influence this behavior because there is
no
user-facing API
We should use the fire timestamp as the default output timestamp.
