## Context The `twenty_event_streams_live_total` gauge counted live streams by SCANning every `workspace:*:activeStreams` key and summing set cardinalities. A full metric refresh walks the entire Redis keyspace, on every server instance, and its cost grows with unrelated cache data rather than with the number of streams. ## What changed Adds a metric-only sorted set, `activeStreamExpirations`. Members are `workspaceId:eventStreamChannelId`, scores are expiration timestamps: - Create and successful heartbeat refresh: `ZADD` with score `now + EVENT_STREAM_TTL_MS` - Destroy and stale cleanup: `ZREM` - Gauge read: `ZREMRANGEBYSCORE` + `ZCARD` in one transaction The scan-and-count cache helper is removed. Scores are written at the same moments the stream key TTL is set, so a member expires exactly when its stream key would. Any missed cleanup (crashed pod, failed heartbeat) resolves itself at the next gauge read. Metric writes are best effort: failures are logged and never affect stream creation, refresh, or cleanup. Existing stream keys and application behavior are unchanged, and no migration is needed. ## Tradeoffs - One extra `ZADD` per 30-second heartbeat - During a rolling deploy, streams owned by old pods appear in the gauge after their next heartbeat (undercount bounded by one heartbeat interval) - A destroy racing a concurrent refresh can leave one orphaned member until its score lapses (gauge over-counts by 1 for at most one TTL) ## Testing - Unit coverage for the sorted-set cache helpers and the stream lifecycle (create, refresh success/failure, destroy, stale cleanup) - `npx nx typecheck twenty-server`, targeted Oxlint, 14 tests passing

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

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.
