Added configurable page sizes for GitHub GraphQL API queries to prevent `RESOURCE_LIMITS_EXCEEDED` errors with large GitHub organizations.
**Default Values Changed:**
To prevent `RESOURCE_LIMITS_EXCEEDED` errors by default, the page sizes have been reduced to 50% of previous values:
- `teams`: 50 → **25**
- `teamMembers`: 100 → **50**
- `organizationMembers`: 100 → **50**
- `repositories`: 50 → **25**
**New Configuration:**
You can now configure page sizes in `app-config.yaml` to customize GitHub API resource consumption:
**For `githubOrg` provider (users and teams):**
```yaml
catalog:
providers:
githubOrg:
- id: production
githubUrl: https://github.com
orgs: ['your-org']
schedule:
frequency: { minutes: 30 }
timeout: { minutes: 3 }
# Optional: Customize page sizes (defaults shown below)
pageSizes:
teams: 25 # Default: 25
teamMembers: 50 # Default: 50
organizationMembers: 50 # Default: 50
repositories: 25 # Default: 25
```
**For `github` provider (repositories):**
```yaml
catalog:
providers:
github:
myorg:
organization: 'your-org'
catalogPath: '/catalog-info.yaml'
schedule:
frequency: { minutes: 30 }
timeout: { minutes: 3 }
# Optional: Customize page sizes (defaults shown below)
pageSizes:
repositories: 25 # Default: 25
```
**Breaking Changes:**
The default page sizes have been reduced by 50% to prevent `RESOURCE_LIMITS_EXCEEDED` errors with large organizations. This may result in:
- ✅ **More stable syncs** for large organizations (200+ teams)
- ⚠️ **Slightly more API calls** due to additional pagination
- ⚠️ **Slightly slower sync times** (typically 10-20% slower)
If you need the previous behavior, you can restore the old values in your configuration:
```yaml
pageSizes:
teams: 50
teamMembers: 100
organizationMembers: 100
repositories: 50
```
**Benefits:**
- Prevents `RESOURCE_LIMITS_EXCEEDED` errors for large GitHub organizations (200+ teams)
- Configurable per provider instance
- No performance impact for smaller organizations
- All data still synced through pagination

- `githubUrl`: The target that this provider should consume
- `orgs` (optional): The list of the GitHub orgs to consume. If you only list a single org the generated group entities will use the `default` namespace, otherwise they will use the org name as the namespace. By default the provider will consume all accessible orgs on the given GitHub instance (support for GitHub App integration only).
- `schedule`: The refresh schedule to use, matches the structure of [`SchedulerServiceTaskScheduleDefinitionConfig`](https://backstage.io/docs/reference/backend-plugin-api.schedulerservicetaskscheduledefinitionconfig/)
- `pageSizes` (optional): Configure page sizes for GitHub GraphQL API queries to prevent `RESOURCE_LIMITS_EXCEEDED` errors with large organizations. See [Page Sizes Configuration](#page-sizes-configuration) below for details.
### Page Sizes Configuration
For large GitHub organizations (200+ teams), you may encounter `RESOURCE_LIMITS_EXCEEDED` errors due to GitHub's GraphQL API resource limits. You can configure page sizes to reduce the number of records fetched per API request:
```yaml title="app-config.yaml"
catalog:
providers:
githubOrg:
- id: production
githubUrl: https://github.com
orgs: ['large-org']
schedule:
frequency: { hours: 1 }
timeout: { minutes: 50 }
pageSizes:
teams: 25 # Default: 25
teamMembers: 50 # Default: 50
organizationMembers: 50 # Default: 50
repositories: 25 # Default: 25
```
**Configuration Options:**
- `teams`: Number of teams to fetch per page when querying organization teams (default: 25)
- `teamMembers`: Number of team members to fetch per page when querying team members (default: 50)
- `organizationMembers`: Number of organization members to fetch per page (default: 50)
- `repositories`: Number of repositories to fetch per page (default: 25)
**Note:** Reducing page sizes will result in more API calls and slightly longer sync times, but will prevent resource limit errors for large organizations.
