KIP-813 — Shareable State Stores
Accepted Kafka 3.8 Streams
KIP-813 introduces shareable state stores in Kafka Streams, allowing multiple Streams applications to read from a single physical state store without each application maintaining its own changelog-backed replica. Today each application that needs the same state must independently replicate the full changelog topic, duplicating storage and reprocessing costs.
