# Limits

## Sizes

| Limit | Value |
| --- | --- |
| Variations of a string, number or object flag | 2 to 20 |
| A variation's value | 32 KB of JSON |
| Rules per config | 100 |
| A rule's description | 200 characters |
| Clauses per rule | 10 |
| Values per clause | 1,000 |
| Individual target values per config | 10,000 |
| A segment's included and excluded targetingKeys | 10,000 each |
| An environment's compiled flags | 8 MB |
| An evaluation context | 8 KB |
| A request to the API | 1 MiB |

A change that would make an environment's compiled flags larger than 8 MB (a long list of targets,
or a segment many flags use) is refused with `400 snapshot_too_large`, and nothing changes. Move
long lists into segments, or trim them.

**Requests to the API are at most 1 MiB,** so one config or segment can't carry every list its
limits allow if the values are long: 10,000 targets of 120 characters don't fit in one request.
Typical ID lists (thousands of user or account IDs) fit; longer ones must be split across segments
or kept short.

## Evaluation rate limits

Per environment, on `https://flags.ezghcloud.com`:

| Limit | Default |
| --- | --- |
| OFREP requests | 2,000 a second, in bursts of up to 10,000 |
| Flag downloads by server providers | 10 a second, in bursts of up to 100 |
| Open server provider streams | 500 |
| Open client streams (web providers with `live: true`) | 10,000 |
| Requests with a missing or wrong key, per client address | 20 a minute |

Over a limit answers `429` with `Retry-After`; EZGH's providers wait for it and retry. Server
providers evaluate locally, so evaluations don't count. To raise a limit, contact support.

## Quotas

| Quota | Default |
| --- | --- |
| `flags.flags.perProject` | 2,000 flags per project (archived flags count) |
| `flags.environments.perProject` | 20 environments per project |
| `flags.segments.perProject` | 200 segments per project |
| `flags.sdkKeys.perProject` | 200 unrevoked SDK keys per project |

Creating past a quota answers `409 quota_exceeded`. See and request quotas in
[Service quotas](/quotas).
