## Problem The cron-trigger cache key (`module:workflow:workflow-cron-triggers`) can get stuck without a TTL, silently halting **all** cron-triggered workflows for a whole tenant until the key is manually deleted from Redis. Repro path: 1. Cache miss → DB-scan branch runs. 2. Inner loop writes triggers via `hashSet` (creates the key, **no TTL yet**). 3. Worker crashes / OOMs / gets killed by a deploy between any `hashSet` and the trailing `expire(1h)` call. 4. Key now exists with TTL = `-1` and a partial set of fields. 5. Next tick: `hashGetValues` returns those fields → `cachedValues.length > 0` → **cache-hit branch** → `expire` is never called. 6. Key has no TTL, so it never auto-expires. The DB-scan branch never runs again. New / missing triggers are never picked up. Workflows go silent. Observed in production: cache key with `TTL: no limit` and 121 fields. Deleting the key restored normal behaviour (next tick rebuilt with TTL ~3600). ## Fix Set the TTL right after first value is added ## Monitoring Added a "Cache miss" log count in workflow dashboard, counted among the last 6 hours.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
