Reviewed the existing point-lookup reservation and counter usage to confirm it should remain the source of truth while staff search moved to an inverted index. New search routes deliberately avoided scanning keyspace.
Used the existing key-value store to add a per-identifier index for active holds, with add on reserve, remove on release, and pruning of expired entries on read. Enabled single-key lookup without scanning all holds.
Implemented bounded key-pattern scanning over existing stock and hold keys with literal escaping, case handling, result caps, and a separate replica reader. Verified only with an in-memory fake and unit tests, not against a live cluster.
Used as durable backing for the SMS queue, with persistence and a dedicated volume in the compose setup and a real server process for end-to-end checks. Health checks and queued jobs behaved as expected.
