kennknowles opened a new issue, #18848: URL: https://github.com/apache/beam/issues/18848
The use of a reducer that adds all of the elements that it consumes to a list is the primary way in which this occurs - if instead, we produce a filtered iterable, or a collection of filtered iterables, we can lazily iterate over all of the contained elements without having to buffer all of the elements. For an example of where this occurs, see `Concatenate` in `FlinkBatchPortablePipelineTranslator`. Imported from Jira [BEAM-4228](https://issues.apache.org/jira/browse/BEAM-4228).
