Subject [jira] [Comment Edited] (KAFKA-6692) Kafka Streams internal topics should be prefixed with an underscore
Date Tue, 20 Mar 2018 18:03:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16406777#comment-16406777

-----------------------------------------------------------------

All internal topics are prefixed with the user specified {{application.id}}. It's {{"<application.id>-<someName>-repartition"}} and
{{"<application.id>-<someName>-changelog"}}. I am wondering it this is sufficient
or not? What does adding two underscored improve?

>                 URL: https://issues.apache.org/jira/browse/KAFKA-6692
>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>    Affects Versions: 1.0.0
>            Reporter: Yeva Byzek
>            Priority: Major
>
> Issue: users cannot quickly/easily differentiate between their explicitly created topics
from internal topics that Kafka Streams uses, e.g. {{*-changelog}} and {{*-repartition}}
>  
> Proposed solution: Kafka Streams internal topics should be prefixed with an underscore
> Value add: ability to introspect kstreams and be able to *know* a set of topics are associated
with a topology.  This can help downstream tooling to do cool visualizations and tracking
