Current documented limits
| Constraint | Current value | Scope | Verified source |
|---|---|---|---|
| generation-specific maximumThe maximum depends on generation and invocation type. | 1st gen: 540s; 2nd gen HTTP: 60m; scheduled: 30m; event: 540s | Cloud Run functions | Google CloudAug 22, 2026 |
| maximum function memoryProject and regional quotas also govern aggregate memory use. | 1st gen: 8 GiB; 2nd gen: 32 GiB | Generation specific | Google CloudAug 22, 2026 |
| request and event payloadHTTP request/response, event, and streaming paths have different documented ceilings. | Generation and invocation-type specific | Cloud Run functions | Google CloudAug 22, 2026 |
| control-plane API ratesDeployment and management API quotas are separate from requests to deployed functions. | Read and write quotas vary by generation and region | Per project | Google CloudAug 22, 2026 |
How to apply Google Cloud Functions limits safely
The monitored baseline covers generation-specific maximum, maximum function memory, request and event payload, control-plane API rates. Treat these as separate constraints rather than one platform-wide capacity number: a workload can fit one row and still fail another because the plan, model, endpoint, runtime, region, invocation mode, or account scope differs.
- Match the production workload to the exact scope printed beside each value and confirm it in the active Google Cloud Functions console, configuration, or response headers.
- Measure the serialized request, token volume, duration, concurrency, storage, or connection demand at realistic percentiles, then preserve headroom for bursts and retries.
- Check every adjacent layer—client, SDK, gateway, proxy, queue, database, and downstream service—for a smaller effective limit before changing architecture.
