[jira] [Commented] (KAFKA-3511) Provide built-in aggregators sum() and avg() in Kafka Streams DSL

    [ https://issues.apache.org/jira/browse/KAFKA-3511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15286364#comment-15286364 ] 

Eno Thereska commented on KAFKA-3511:
-------------------------------------

[~imandhan] Thanks for picking this up. Is it ok if I help out with this, perhaps creating the initial template and one or two aggregate functions? Or are you actively working on it? Thanks.
