Pradeep Gollakota commented on KAFKA-1175:
------------------------------------------
In the proposal, [~jkreps] talks about a couple of use cases at LinkedIn.
# Group a set of topics that are related by the application area (ads, search,
etc.)
# Group a set of topics based on usage paradigm (tracking, metrics, etc.)
At Lithium, we have an extension of those use cases. We have multiple products
that are deployed for different customers. So we need to partition by
customer_id and product_id. So, we may have hierarchical topics of the
following nature:
# /p1/google/tracking/search/click_events
# /p1/google/tracking/community/message_create_events
# /p1/linkedin/tracking/search/click_events
# /p1/linkedin/tracking/community/message_create_events
# /p2/apache/tracking/core/user_ident_event
> Hierarchical Topics
