It’s a parallel reduction operation, analogous to the Shuffle phase of a Map/Shuffle/Reduce-style algorithm. The input to GroupByKey is a collection of key/value pairs that represents a multimap, where the collection contains multiple pairs that have the same key, but different values. Given such a collection, you use GroupByKey to collect all of the values associated with each unique key.</p> <p>In this task, we are going to implement a <a href="https://beam.apache.org/releases/pydoc/2.11.0/apache_beam.transforms.core.html#apache_beam.transforms.core.GroupByKey"> GroupByKey</a> transform that groups words by its first letter. </p> <br> <br> <div class='hint'>Refer to <a href="https://beam.apache.org/releases/pydoc/2.11.0/apache_beam.transforms.core.html#apache_beam.transforms.core.GroupByKey">GroupByKey</a> to solve this problem</div> </html> " /> |
