## Context
`twenty_event_streams_live_total` (an observable gauge) calls
`getTotalActiveStreamCount()` →
`scanAndCountSetMembers('workspace:*:activeStreams')`, which runs a
full-keyspace `SCAN MATCH` over the entire Redis DB **on every metrics
scrape, on every pod**. `SCAN MATCH` walks every key (filtering only the
output), and the subscriptions namespace shares the node with the
workspace metadata cache (~190k keys in our prod), so this was the
dominant Redis command (billions of `SCAN` calls) to count a handful of
sets.
## What this does
Cache the count and refresh it via the scan at most once per
`ACTIVE_STREAM_COUNT_REFRESH_MS` (5 min) per pod, instead of on every
scrape. Steady-state scrapes return the cached value; the authoritative
scan still runs periodically so the gauge stays fresh.
Single-method change; no new Redis keys, no data-model changes.

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.
