From 4526ba0ad1687ff6d938565b01df5ea6a66cbc1c Mon Sep 17 00:00:00 2001 From: InduwaraSMPN Date: Fri, 3 Oct 2025 02:01:11 +0530 Subject: [PATCH 01/12] feat(catalog-incremental): Implement OpenChoreo incremental ingestion backend module Adds a new backend module enabling scalable, cursor-based incremental catalog ingestion from OpenChoreo. This module implements: - Burst-based processing with configurable rest/burst cycles. - Three-phase traversal (Organizations -> Projects -> Components). - State persistence and resumable ingestion using database tracking. - Health and management API endpoints for monitoring and control. - Automated database migrations for state tables. --- .../.eslintrc.js | 1 + .../README.md | 165 +++ .../config.d.ts | 54 + .../dev/index.ts | 93 ++ .../migrations/20221116073152_init.js | 184 +++ .../package.json | 71 ++ ...ncrementalIngestionDatabaseManager.test.ts | 86 ++ ...oreoIncrementalIngestionDatabaseManager.ts | 1001 +++++++++++++++++ .../src/database/errors.ts | 52 + .../src/database/migrations.ts | 35 + .../src/database/tables.ts | 123 ++ .../OpenChoreoIncrementalIngestionEngine.ts | 465 ++++++++ .../src/index.ts | 40 + .../src/module.ts | 25 + .../src/module/WrapperProviders.test.ts | 119 ++ .../src/module/WrapperProviders.ts | 190 ++++ ...IncrementalIngestionEntityProvider.test.ts | 81 ++ ...oduleIncrementalIngestionEntityProvider.ts | 145 +++ .../src/module/index.ts | 27 + .../openchoreoIncrementalProviderModule.ts | 87 ++ ...penChoreoIncrementalEntityProvider.test.ts | 489 ++++++++ .../OpenChoreoIncrementalEntityProvider.ts | 515 +++++++++ .../src/providers/entityTranslator.ts | 252 +++++ .../src/router/routes.ts | 272 +++++ .../src/types.ts | 201 ++++ 25 files changed, 4773 insertions(+) create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/.eslintrc.js create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/README.md create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/config.d.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/dev/index.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/migrations/20221116073152_init.js create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/package.json create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/database/OpenChoreoIncrementalIngestionDatabaseManager.test.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/database/OpenChoreoIncrementalIngestionDatabaseManager.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/database/errors.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/database/migrations.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/database/tables.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/engine/OpenChoreoIncrementalIngestionEngine.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/index.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/WrapperProviders.test.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/WrapperProviders.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/catalogModuleIncrementalIngestionEntityProvider.test.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/catalogModuleIncrementalIngestionEntityProvider.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/index.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/module/openchoreoIncrementalProviderModule.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/providers/OpenChoreoIncrementalEntityProvider.test.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/providers/OpenChoreoIncrementalEntityProvider.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/providers/entityTranslator.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/router/routes.ts create mode 100644 plugins/catalog-backend-module-openchoreo-incremental/src/types.ts diff --git a/plugins/catalog-backend-module-openchoreo-incremental/.eslintrc.js b/plugins/catalog-backend-module-openchoreo-incremental/.eslintrc.js new file mode 100644 index 00000000..e2a53a6a --- /dev/null +++ b/plugins/catalog-backend-module-openchoreo-incremental/.eslintrc.js @@ -0,0 +1 @@ +module.exports = require('@backstage/cli/config/eslint-factory')(__dirname);

Key changes include: - **`DefaultApiClient`**: Added private methods `wrapResponse` and `buildQueryString` to handle response wrapping and dynamic query parameter construction (supporting cursor/limit or generic params). All relevant GET requests now use `buildQueryString` and wrap the resulting `Response` in a `TypedResponse`. - **`OpenChoreoApiClient`**: - Introduced constructor overloading to support options object. - Replaced simple `getAll*` methods with versions that use cursors/limits (`get*WithCursor`) and return the full `OpenChoreoApiResponse` structure, including pagination data. - Added a private helper `convertToPagedResponse` to normalize API data with pagination fields like `nextCursor`. - Added error handling for non-2xx responses using a new `buildErrorMessage` helper. - Updated imports and exports for better organization. - **Models/Requests**: Updated request types (`ProjectsGetRequest`, `OrganizationsGetRequest`, `ComponentsGetRequest`) to include `cursor` and `limit`. Updated response models to include `nextCursor` in `PaginatedData` and introduced `CursorPaginationOptions` and `CursorPaginatedData`. --- .../src/api/default_api_client.ts | 134 ++++++++--- plugins/openchoreo-api/src/client.ts | 224 ++++++++++++++++-- plugins/openchoreo-api/src/index.ts | 2 +- plugins/openchoreo-api/src/models/requests.ts | 7 +- .../openchoreo-api/src/models/responses.ts | 24 +- 5 files changed, 334 insertions(+), 57 deletions(-) diff --git a/plugins/openchoreo-api/src/api/default_api_client.ts b/plugins/openchoreo-api/src/api/default_api_client.ts index 8e3bf9d2..8fb1ee9a 100644 --- a/plugins/openchoreo-api/src/api/default_api_client.ts +++ b/plugins/openchoreo-api/src/api/default_api_client.ts @@ -56,9 +56,59 @@ export class DefaultApiClient { this.fetchApi = options.fetchApi || { fetch: crossFetch };
