# Redis client (historical batch-jobs path)

The batch-search product (`run_batch_search`, `/agent/batch/{id}`, Hirebase chunk workers) has been removed. `discover_jobs` is the search. Page scrape still uses `/agent/scrape/{id}`.

`lib/batch-jobs/redis.ts` remains the shared Upstash client for credits, search runs, shortlist, seen listings, digest, lab traces, and scrape/crawl jobs. Do not delete it.

## Troubleshooting: values come back as objects

The Upstash Redis client **parses JSON on `GET` by default**. This app stores JSON as a **string** with `SET` and expects a **string** back on `GET`. The client is constructed with `automaticDeserialization: false`. After changing that setting, restart the deployment so a new process picks up the client.

## Required for Redis-backed features

- `UPSTASH_REDIS_REST_URL`
- `UPSTASH_REDIS_REST_TOKEN`

QStash (`QSTASH_TOKEN` and signing keys) is still used by digest fan-out and page-scrape jobs. `BATCH_PUBLIC_APP_URL` must be the app origin (`https://<name>.hf.space`), not the Hugging Face gallery URL.
