Term	Kind	Topic	What it is
Follower Fetching Closest-Replica Fetch, Rack-Aware Consumption	pattern	Streaming Cost	Letting a consumer read from the in-sync replica in its own availability zone instead of from the partition leader, which removes consumer-side cross-zone transfer charges and adds replication delay to every read.
Tiered Storage Remote Storage Offload, Long-Term Log Retention, Hot-Cold Log Tiering	pattern	Streaming Cost	Keeping recent log segments on broker local disk and older ones in object storage, which decouples retention from broker sizing and turns replay from an emergency measure into a routine design tool.
