Gets the element with the maximum value within each aggregation.

Examples

In the following example, we create a pipeline with a PCollection. Then, we get the element with the maximum value in different ways.

Example 1: Maximum element in a PCollection

We use Combine.Globally() to get the maximum element from the entire PCollection.

Example 2: Maximum elements for each key

We use Combine.PerKey() to get the maximum element for each unique key in a PCollection of key-values.
