The 'analytics-eqiad' Kafka cluster hardware is due to be refreshed. We also want to enable Kafka security features. We also want to move this large beefy Kafka cluster out of the 'Analytics Cluster' / Analytics VLAN, and make it a fully productionized Kafka cluster, available for use of production services. We may eventually merge the existent smaller main-* Kafka clusters into these new ones, but we don't have plans to do that within the next year.
This is the parent ticket for the provisioning, upgrade and migration plan for these new clusters.
