| = Gerrit Code Review - Quota |
| |
| Gerrit does not provide out of the box quota enforcement. However, it does |
| support an extension mechanism for plugins to hook into to provide this |
| functionality. The most prominent plugin is the |
| link:https://gerrit.googlesource.com/plugins/quota/[Quota Plugin,role=external,window=_blank]. |
| |
| This documentation is intended to be read by plugin developers. It contains all |
| quota requests implemented in Gerrit-core as well as the metadata that they have |
| associated. |
| |
| == Quota Groups |
| |
| The following quota groups are defined in core Gerrit: |
| |
| === REST API |
| [[rest-api]] |
| |
| The REST API enforces quota after the resource was parsed (if applicable) and before the |
| endpoint's logic is executed. This enables quota enforcer implementations to throttle calls |
| to specific endpoints while knowing the general context (user and top-level entity such as |
| change, project or account). |
| |
| If the quota enforcer wants to throttle HTTP requests, they should use |
| link:quota.html#http-requests[HTTP Requests] instead. |
| |
| The quota groups used for checking follow the exact definition of the endoint in the REST |
| API, but remove all IDs. The schema is: |
| |
| /restapi/<ENDPOINT>:<HTTP-METHOD> |
| |
| Examples: |
| |
| [options="header",cols="1,6"] |
| |======================= |
| |HTTP call |Quota Group |Metadata |
| |GET /a/changes/1/revisions/current/detail |/changes/revisions/detail:GET |CurrentUser, Change.Id, Project.NameKey |
| |POST /a/changes/ |/changes/:POST |CurrentUser |
| |GET /a/accounts/self/detail |/accounts/detail:GET |CurrentUser, Account.Id |
| |======================= |
| |
| The user provided in the check's metadata is always the calling user (having the |
| impersonation bit and real user set in case the user is impersonating another user). |
