From a98f37fb8ebe26636bdea81ac2769ce8663aa9d4 Mon Sep 17 00:00:00 2001 From: Andreas Klos Date: Tue, 16 Dec 2025 13:05:24 +0100 Subject: [PATCH 1/7] refactor: Enhance sitemap extraction and summarization features - Added support for configurable sitemap parsing via environment variable `SITEMAP_PARSER` with options: `docusaurus`, `astro`, and `generic`. - Introduced new config map for extractor sitemap settings. - Updated `PageSummaryEnhancer` to group documents by URL for non-numeric pages and maintain separation for paged documents. - Enhanced `LangchainSummarizer` to respect max concurrency settings during summarization. - Improved error logging for source uploads in `DefaultSourceUploader`. - Added comprehensive tests for new sitemap parsing functions and summarization logic. - Updated README and documentation to reflect changes and provide guidance on memory management for backend pods. --- infrastructure/README.md | 2 + .../_admin_backend_and_extractor_helpers.tpl | 4 + .../rag/templates/extractor/configmap.yaml | 8 + .../rag/templates/extractor/deployment.yaml | 2 + infrastructure/rag/values.yaml | 19 +- libs/README.md | 1 + .../api_endpoints/default_source_uploader.py | 6 +- .../page_summary_enhancer.py | 77 +++++-- .../impl/summarizer/langchain_summarizer.py | 30 ++- .../tests/langchain_summarizer_test.py | 57 +++++ .../tests/page_summary_enhancer_test.py | 127 +++++++++++ .../extractor_api_lib/dependency_container.py | 36 +++- .../impl/extractors/sitemap_extractor.py | 74 ++++++- .../impl/settings/sitemap_settings.py | 18 ++ .../impl/utils/sitemap_extractor_utils.py | 201 +++++++++++++++--- .../tests/sitemap_extractor_utils_test.py | 106 +++++++++ .../answer_generation_prompt.py | 22 +- 17 files changed, 700 insertions(+), 90 deletions(-) create mode 100644 infrastructure/rag/templates/extractor/configmap.yaml create mode 100644 libs/admin-api-lib/tests/langchain_summarizer_test.py create mode 100644 libs/admin-api-lib/tests/page_summary_enhancer_test.py create mode 100644 libs/extractor-api-lib/src/extractor_api_lib/impl/settings/sitemap_settings.py create mode 100644 libs/extractor-api-lib/tests/sitemap_extractor_utils_test.py diff --git a/infrastructure/README.md b/infrastructure/README.md index a6e5ba0f..fddffec4 100644 --- a/infrastructure/README.md +++ b/infrastructure/README.md @@ -257,6 +257,8 @@ frontend: The following values should be adjusted for the deployment: +> ⓘ INFO: If the backend pod gets `OOMKilled` (exit code `137`) on local k3d/Tilt setups, reduce `backend.workers` (each uvicorn worker is a separate Python process), disable reranking `RERANKER_ENABLED: false` or pin a smaller Flashrank model (e.g. `RERANKER_MODEL: ms-marco-TinyBERT-L-2-v2`), and/or increase the memory available to Docker/k3d. + ```yaml backend: secrets: diff --git a/infrastructure/rag/templates/_admin_backend_and_extractor_helpers.tpl b/infrastructure/rag/templates/_admin_backend_and_extractor_helpers.tpl index 5f851477..0f860234 100644 --- a/infrastructure/rag/templates/_admin_backend_and_extractor_helpers.tpl +++ b/infrastructure/rag/templates/_admin_backend_and_extractor_helpers.tpl @@ -68,6 +68,10 @@ {{- printf "%s-source-uploader-configmap" .Release.Name | trunc 63 | trimSuffix "-" -}} {{- end -}} +{{- define "configmap.extractorSitemapName" -}} +{{- printf "%s-extractor-sitemap-configmap" .Release.Name | trunc 63 | trimSuffix "-" -}} +{{- end -}} + # image {{- define "adminBackend.fullImageName" -}} {{- $tag := default .Chart.AppVersion .Values.adminBackend.image.tag -}} diff --git a/infrastructure/rag/templates/extractor/configmap.yaml b/infrastructure/rag/templates/extractor/configmap.yaml new file mode 100644 index 00000000..5f02f2c0 --- /dev/null +++ b/infrastructure/rag/templates/extractor/configmap.yaml @@ -0,0 +1,8 @@ +apiVersion: v1 +kind: ConfigMap +metadata: + name: {{ template "configmap.extractorSitemapName" . }} +data: + {{- range $key, $value := .Values.extractor.envs.sitemap }} + {{ $key }}: {{ $value | quote }} + {{- end }} diff --git a/infrastructure/rag/templates/extractor/deployment.yaml b/infrastructure/rag/templates/extractor/deployment.yaml index adfd2e38..7b5e16de 100644 --- a/infrastructure/rag/templates/extractor/deployment.yaml +++ b/infrastructure/rag/templates/extractor/deployment.yaml @@ -110,6 +110,8 @@ spec: envFrom: -
