> Java's org.apache.beam.sdk.transforms.Sample.any will return a PCollection with bounded size (filtering strategy).
> The closest python eqiuvalent is beam.Sample.FixedSizeGlobally(n) whover, this version uses a combiner strategy, returning a list with n elements; which does not scale if n is "bigger than what fits in memory".
