## Why App installs on cloud intermittently fail with a 504, surfacing in Sentry as `Migration action 'update' for 'logicFunction' failed` + `Failed to rollback transaction: Query runner already released`. This is **temporary instrumentation** to pin down where the time goes — to be reverted once the bottleneck is fixed. Everything is greppable via `[install-perf]` and marked `// TODO(install-perf)`. ## What the local repro already told us I instrumented the manifest-sync/migration path and ran a local harness (new skipped spec) installing **1 / 8 / 30 logic functions**, for both create and the checksum-bump **update** (the incident path): | stage (N=30, update) | ms | |---|---| | flat-maps recompute | ~1 | | build migration | ~11 | | transaction (all actions + commit) | ~79 | | post-commit cache invalidate | ~6 | | **full sync** | **~135** | Nothing approached 1s, let alone 10s; no slow queries logged. So the migration/cache code is **not** the algorithmic cause. Given the in-transaction `UPDATE ... WHERE id=?` is intrinsically fast, a >10s in prod almost certainly means it was **blocked on a lock**, and the 10s node-pg `query_timeout` (`core.datasource.ts`) then killed the connection → the observed errors + 504. Local can't reproduce prod lock contention / table sizes, hence this instrumentation. ## What this adds (all `TODO`-marked) - **hrtime per-stage timing** — flat-maps recompute, build vs run, per-action (`>50ms`), transaction summary, post-commit cache invalidation. Uses `process.hrtime` because the integration harness enables fake timers (so `Date.now()` is useless there). - **`maxQueryExecutionTime`** slow-query logging on the core datasource (logs the offending SQL). - **Scoped `SET LOCAL lock_timeout = '8s'`** on the migration transaction (below the 10s `query_timeout`) → a blocked action fails fast with a clear *"canceling statement due to lock timeout"* instead of the opaque connection kill. - **Best-effort `pg_stat_activity` snapshot on failure** (on a fresh pooled connection) to identify the blocking session, plus a **guarded rollback** so a released connection stops masking the real error. - **Skipped local perf harness** (`logic-function-install-performance.integration-spec.ts`) — run manually with `nx test:integration:with-db-reset -- --testPathPattern "logic-function-install-performance"`. ## How we'll use it Deploy, reproduce the failing install, and read the `[install-perf]` logs: the per-action timing names the action, the `lock_timeout` message + `pg_stat_activity` snapshot name the **blocking** query/PID. Then revert this PR and fix the actual contention. Typecheck (`nx typecheck twenty-server`) is clean.

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.
