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.
