From a83263ff5ca9d4c5943b8031335fa41df58c9e05 Mon Sep 17 00:00:00 2001 From: InduwaraSMPN Date: Sun, 14 Dec 2025 13:30:23 +0530 Subject: [PATCH 01/38] Adds robust cursor-based pagination with API page size config Introduces generic helpers and refactors API calls to use cursor-based pagination for all list endpoints, improving scalability and reliability for large data sets. Updates OpenAPI schema and client types to support metadata-driven pagination, replaces page/size parameters with limit/continue, and implements a default max page size for efficiency. Enhances error handling for paginated requests and prevents infinite loops. Refactors several backend services and entity providers to leverage the new pagination utilities, ensuring consistent resource synchronization across organizations, projects, and components. Motivated by the need for reliable handling of large deployments and to align with upstream OpenChoreo API changes. --- .../openapi/openchoreo-api.yaml | 108 ++- .../generated/openchoreo/component-type.ts | 9 +- .../src/generated/openchoreo/index.ts | 1 -

seconds - interval between bursts during active ingestion + restLength: 30 # minutes - rest period after completing full ingestion + chunkSize: 50 # entities per API request +``` + +## How It Works + +### Burst-Based Processing + +The provider uses a burst-and-rest cycle to control load: + +1. **Burst Phase**: Processes entities continuously for `burstLength` seconds +2. **Interstitial Phase**: Pauses for `burstInterval` seconds between bursts +3. **Rest Phase**: After completing a full ingestion cycle, rests for `restLength` minutes before starting again + +This approach prevents overwhelming the API server while ensuring regular catalog updates. + +### Cursor-Based Pagination + +The provider traverses OpenChoreo resources in three phases using continuation token-based pagination: + +1. **Organizations Phase**: Fetches all organizations and builds an organization queue +2. **Projects Phase**: For each organization, fetches all projects and builds a project queue +3. **Components Phase**: For each project, fetches all components and their APIs + +Each phase maintains its own API cursor (`orgApiCursor`, `projectApiCursor`, `componentApiCursor`) allowing safe resumption after interruptions. The cursor state tracks: + +- Current phase (`orgs`, `projects`, `components`) +- API pagination cursors for each resource type +- Queues of organizations and projects to process +- Current position in each queue + +#### Pagination Mechanism + +The provider uses continuation token-based pagination with the following characteristics: + +- **Continuation Tokens**: Opaque tokens that mark the position in the result set +- **Resource Version**: Kubernetes-style resource versioning for consistency +- **HasMore Flag**: Indicates if more results are available +- **Limit Parameter**: Controls the number of items per page (0-500, default 100) + +Example response structure: +```json +{ + "data": { + "success": true, + "data": { + "items": [...], + "metadata": { + "resourceVersion": "12345", + "continue": "opaque-token", + "hasMore": true + } + } + } +} +``` + +#### HTTP 410 Error Handling + +When a continuation token expires (HTTP 410 Gone), the provider automatically: + +1. Detects the expired token error +2. Logs a warning with phase and cursor information +3. Resets the cursor to start from the beginning +4. Retries the ingestion process + +This ensures robust handling of long-running ingestion processes where tokens may expire. + +### Requirements + +Your OpenChoreo backend must support continuation token-based pagination. The provider validates API support at startup and requires: + +- `metadata.resourceVersion` field in list responses +- `metadata.continue` field for pagination tokens +- `metadata.hasMore` flag to indicate more results +- Support for `limit` and `continue` query parameters +- HTTP 410 response for expired continuation tokens + +### State Persistence + +All ingestion state is persisted to the database: + +- Cursors are saved after each burst +- Entity references are tracked for staleness detection +- Progress can resume from the last successful checkpoint +- Removed entities are detected by comparing current and previous ingestion snapshots + +## Management API + +The module provides REST API endpoints for monitoring and managing incremental ingestion: + +- `GET /api/catalog/incremental/health` - Health check status for all providers +- `GET /api/catalog/incremental/providers` - List all registered incremental providers +- `GET /api/catalog/incremental/providers/{name}/status` - Get detailed status for a specific provider +- `POST /api/catalog/incremental/providers/{name}/reset` - Reset provider state to start fresh ingestion +- `POST /api/catalog/incremental/providers/{name}/refresh` - Trigger immediate refresh of provider data + +## Database Migrations + +The module includes automatic database migrations to create the necessary tables for state persistence: + +- `openchoreo_incremental_ingestion_state` - Stores cursor state and ingestion metadata +- `openchoreo_incremental_entity_refs` - Tracks entity references for staleness detection + +These migrations run automatically when the module is first loaded. + +## Migration from Legacy Provider + +If you were previously using the basic `catalog-backend-module-openchoreo` provider: + +1. **Remove the old provider**: Remove the basic OpenChoreo provider module from your backend +2. **Add this incremental module**: Register this module as shown in the Installation section +3. **Update configuration**: Add the `incremental` configuration block (or use defaults) +4. **Verify API support**: Ensure your OpenChoreo API supports cursor-based pagination endpoints + +## Extension Points + +The module provides extension points for advanced use cases: + +### Incremental Provider Extension Point + +You can extend the module with custom incremental entity providers: + +```typescript +import { + openchoreoIncrementalProvidersExtensionPoint, + type OpenChoreoIncrementalProviderExtensionPoint, +} from '@openchoreo/plugin-catalog-backend-module-openchoreo-incremental';

cursor-based pagination with burst and rest cycles, providing optimal memory consumption, scalability, and controlled load for large OpenChoreo installations. + +## Installation + +Add the incremental provider module to your backend: + +```typescript +// packages/backend/src/index.ts +backend.add( + import('@openchoreo/plugin-catalog-backend-module-openchoreo-incremental'), +); +``` + +## Configuration + +```yaml +openchoreo: + baseUrl: ${OPENCHOREO_API_URL} + token: ${OPENCHOREO_TOKEN} + incremental: + burstLength: 10 # seconds - duration of each processing burst + burstInterval: 30 # seconds - interval between bursts during active ingestion + restLength: 30 # minutes - rest period after completing full ingestion + chunkSize: 50 # entities per API request +``` + +## How It Works + +### Burst-Based Processing + +The provider uses a burst-and-rest cycle to control load: + +1. **Burst Phase**: Processes entities continuously for `burstLength` seconds +2. **Interstitial Phase**: Pauses for `burstInterval` seconds between bursts +3. **Rest Phase**: After completing a full ingestion cycle, rests for `restLength` minutes before starting again + +This approach prevents overwhelming the API server while ensuring regular catalog updates. + +### Cursor-Based Pagination + +The provider traverses OpenChoreo resources in three phases using continuation token-based pagination: + +1. **Organizations Phase**: Fetches all organizations and builds an organization queue +2. **Projects Phase**: For each organization, fetches all projects and builds a project queue +3. **Components Phase**: For each project, fetches all components and their APIs + +Each phase maintains its own API cursor (`orgApiCursor`, `projectApiCursor`, `componentApiCursor`) allowing safe resumption after interruptions. The cursor state tracks: + +- Current phase (`orgs`, `projects`, `components`) +- API pagination cursors for each resource type +- Queues of organizations and projects to process +- Current position in each queue + +#### Pagination Mechanism + +The provider uses continuation token-based pagination with the following characteristics: + +- **Continuation Tokens**: Opaque tokens that mark the position in the result set +- **Resource Version**: Kubernetes-style resource versioning for consistency +- **HasMore Flag**: Indicates if more results are available +- **Limit Parameter**: Controls the number of items per page (0-500, default 100) + +Example response structure: +```json +{ + "data": { + "success": true, + "data": { + "items": [...], + "metadata": { + "resourceVersion": "12345", + "continue": "opaque-token", + "hasMore": true + } + } + } +} +``` + +#### HTTP 410 Error Handling + +When a continuation token expires (HTTP 410 Gone), the provider automatically: + +1. Detects the expired token error +2. Logs a warning with phase and cursor information +3. Resets the cursor to start from the beginning +4. Retries the ingestion process + +This ensures robust handling of long-running ingestion processes where tokens may expire. + +### Requirements + +Your OpenChoreo backend must support continuation token-based pagination. The provider validates API support at startup and requires: + +- `metadata.resourceVersion` field in list responses +- `metadata.continue` field for pagination tokens +- `metadata.hasMore` flag to indicate more results +- Support for `limit` and `continue` query parameters +- HTTP 410 response for expired continuation tokens + +### State Persistence + +All ingestion state is persisted to the database: + +- Cursors are saved after each burst +- Entity references are tracked for staleness detection +- Progress can resume from the last successful checkpoint +- Removed entities are detected by comparing current and previous ingestion snapshots + +## Management API + +The module provides REST API endpoints for monitoring and managing incremental ingestion: + +- `GET /api/catalog/incremental/health` - Health check status for all providers +- `GET /api/catalog/incremental/providers` - List all registered incremental providers +- `GET /api/catalog/incremental/providers/{name}/status` - Get detailed status for a specific provider +- `POST /api/catalog/incremental/providers/{name}/reset` - Reset provider state to start fresh ingestion +- `POST /api/catalog/incremental/providers/{name}/refresh` - Trigger immediate refresh of provider data + +## Database Migrations + +The module includes automatic database migrations to create the necessary tables for state persistence: + +- `openchoreo_incremental_ingestion_state` - Stores cursor state and ingestion metadata +- `openchoreo_incremental_entity_refs` - Tracks entity references for staleness detection + +These migrations run automatically when the module is first loaded. + +## Migration from Legacy Provider + +If you were previously using the basic `catalog-backend-module-openchoreo` provider: + +1. **Remove the old provider**: Remove the basic OpenChoreo provider module from your backend +2. **Add this incremental module**: Register this module as shown in the Installation section +3. **Update configuration**: Add the `incremental` configuration block (or use defaults) +4. **Verify API support**: Ensure your OpenChoreo API supports cursor-based pagination endpoints + +## Extension Points + +The module provides extension points for advanced use cases: + +### Incremental Provider Extension Point + +You can extend the module with custom incremental entity providers: + +```typescript +import { + openchoreoIncrementalProvidersExtensionPoint, + type OpenChoreoIncrementalProviderExtensionPoint, +} from '@openchoreo/plugin-catalog-backend-module-openchoreo-incremental';
