SUMMARY:The Partition Tax: A Playbook for Right-Sizing Your Kafka Clusters
LOCATION:Room 2012
DESCRIPTION:Charles Larrieu Casias\n\nInternal research across sophisticate
 d Kafka users suggests 40–70% of their cluster spend is wasted on excess
  partitions. These aren't beginners — Kafka simply makes over-provisioni
 ng the path of least resistance\, and once a topic is keyed\, you can't ea
 sily take partitions back. This talk lays out a practical\, layered strate
 gy for getting that spend back\, organized by who can act and when. First\
 , prevent: governance guardrails that stop new sprawl at provisioning time
  without turning the platform team into a ticket queue. Then clean: use co
 st attribution and chargeback to show each team their own waste and hold t
 hem accountable to the cost. Then fix the root cause: slow\, IO-bound cons
 umers are the most common reason teams reach for more partitions. Lots of 
 partitions are not the answer. Share groups / queues for Kafka is not the 
 answer. The real answer is parallel and concurrent consumption that preser
 ves per-key ordering. Finally\, patch: what "lies" a Kafka proxy can tell 
 to patch up infrastructure deficiencies\, from using virtualization to con
 solidate non-prod and concentrating low-volume topics to an experimental a
 pproach to unblocking a slow consumer without touching its code. You'll le
 ave with a concrete checklist for auditing partition waste in your own clu
 sters and a decision framework for which layer to reach for\, mapped to yo
 ur ordering requirements and your org's constraints. By attending this ses
 sion\, your contact information may be shared with the sponsor for relevan
