1.1.1 (2026-07-24)

Fixed

• Client tracks metadata only for topics it actually uses. Previously the periodic refresh folded every topic ever seen into one request and health-gated the whole set, absorbing the entire cluster catalog and never pruning it — so one deleted topic stormed :error logs every cycle and discarded the whole refresh, including fresh leader data for in-use topics (a liveness bug). The client now refreshes only used topics, merges whatever it gets, and logs unavailable used topics edge-triggered (:warning/:info) instead of :error every cycle. Behavior change: the catalog is no longer kept warm; first use of a new topic costs one metadata fetch.

• Metadata refresh no longer stalls the client on a deleted-but-tracked topic. A permanently missing tracked topic re-ran the full retry ladder (~600ms of sleeps) inside the client on every refresh; the retry-sleep now runs only the first time a topic goes missing. Known limitation: the tracked-topic set is not yet pruned, so an ever-growing set of distinct topic names accumulates for the client's lifetime; pruning is planned.

• A consumer that starts its own client scopes it to its own topic. A GenConsumer with no shared :client now seeds the client it starts with initial_topics: [topic], so its first metadata refresh covers just that topic instead of the whole cluster catalog — avoiding N simultaneous whole-catalog fetches at group startup.
