Work Description: brachi-wernick opened a new pull request #17081:
URL: https://github.com/apache/beam/pull/17081
When trying to aggregate input with null value we will fail on null pointer exception, when we deal with high events rate we can have sometimes "broken" events and I don't want them the break all the pipline.
