------------------------------------
Summary: Extract selector as a separate groupBy operator for
KTable aggregations
Key: KAFKA-3337
URL: https://issues.apache.org/jira/browse/KAFKA-3337
Project: Kafka
Issue Type: Sub-task
Reporter: Guozhang Wang
Priority: Blocker
Fix For: 0.10.0.0
Currently KTable aggregation takes a selector and an aggregator, which makes
the function a little bit "heavy". It is better to extract the selector in a
separate groupBy function such that
{code}
table.groupBy(selector).aggregate(aggregator);
{code}
