That item's value comes from the accumulator in the combine function that you specified when applying `Combine`. For example, the Beam provided sum combine function returns a zero value (the sum of an empty input), while the max combine function returns a maximal or infinite value. To have `Combine` instead return an empty `PCollection` if the input is empty, specify `.withoutDefaults` when you apply your `Combine` transform, as in the following code example: -- To stop receiving notification emails like this one, please contact "commits@beam.apache.org" <commits@beam.apache.org>.
