The primary objective of this example is to demonstrate the construction of a pipeline that performs the following tasks:
- Accepts a collection of documents.
- Divides the documents into smaller segments or chunks.
- Computes the embedding vector for each of these chunks.
- Uploads the text chunks along with their associated embeddings to a Vector Database (VDB).
-
The pipeline is designed to process text-based input from various document types. Possible use cases could include structured documents like PDFs, dynamic sources such as web pages, and image-based documents through future Optical Character Recognition (OCR) integration.
-
For this demonstration, the source documents are obtained from RSS feeds combined with a web scraper. The rationale behind this selection includes:
- Emulating practical cyber scenarios: Cybersecurity RSS feeds can serve as the foundation for a comprehensive knowledge database, such as for a security chatbot.
- Minimizing external dependencies: Relying on RSS feeds and web scraping avoids the need for specialized datasets or API keys.
-
The pipeline can accommodate various embedding models that transform text into vectors of floating-point numbers. Several models from Hugging Face, such as
paraphrase-multilingual-mpnet-base-v2,e5-large-v2, andall-mpnet-base-v2, have been evaluated for compatibility. -
For the purposes of this demonstration, the model
all-MiniLM-L6-v2is employed. This model is included via LFS in this repository, and was chosen for its efficiency and compactness, characterized by a smaller embedding dimension of 384.
- The architecture is agnostic to the choice of Vector Database (VDB) for storing embeddings and their metadata. While the present implementation employs Milvus due to its GPU-accelerated indices, the design supports easy integration with other databases like Chroma or FAISS, should the need arise.
The pipeline is composed of three primary components:
-
Document Source Handler: This component is responsible for acquiring and preprocessing the text data. Given that we are using RSS feeds and a web scraper in this example, the handler's function is to fetch the latest updates from the feeds, perform preliminary data cleaning, and standardize the format for subsequent steps.
-
Embedding Generator: This is the heart of the pipeline, which takes the preprocessed text chunks and computes their embeddings. Leveraging the model
all-MiniLM-L6-v2from Hugging Face, the text data is transformed into embeddings with a dimension of 384. -
Vector Database Uploader: Post embedding generation, this module takes the embeddings alongside their associated metadata and pushes them to a Vector Database (VDB). For our implementation, Milvus, a GPU-accelerated vector database, has been chosen.
The selection of specific components and models was influenced by several factors:
-
Document Source Choice: RSS feeds and web scraping offer a dynamic and continuously updating source of data. For the use-case of building a repository for a cybersecurity, real-time information fetching is a reasonable choice.
-
Model Selection for Embeddings:
all-MiniLM-L6-v2was chosen due to its efficiency in generating embeddings. Its smaller dimension ensures quick computations without compromising the quality of embeddings. -
Vector Database: For the purposes of this pipeline, Milvus was chosen due to its popularity, ease of use, and availability.
Before running the pipeline, we need to ensure that the following services are running:
To retrieve the datasets from LFS run the following:
./scripts/fetch_data.py fetch examples- Refer to the Milvus documentation for more details on running Milvus. For the purposes of testing the pipeline, we will launch an instance of Milvus Lite.
From the root of the Morpheus repository, run the following to launch Milvus in a separate terminal:
mkdir -p .tmp/milvusdb
milvus-server --data .tmp/milvusdb-
Pull the Docker image for Triton:
docker pull nvcr.io/nvidia/morpheus/morpheus-tritonserver-models:25.02
-
Run the following to launch Triton and load the
all-MiniLM-L6-v2model:docker run --rm -ti --gpus=all -p8000:8000 -p8001:8001 -p8002:8002 nvcr.io/nvidia/morpheus/morpheus-tritonserver-models:25.02 tritonserver --model-repository=/models/triton-model-repo --exit-on-error=false --model-control-mode=explicit --load-model all-MiniLM-L6-v2
This will launch Triton and only load the
all-MiniLM-L6-v2model. Once Triton has loaded the model, the following will be displayed:+------------------+---------+--------+ | Model | Version | Status | +------------------+---------+--------+ | all-MiniLM-L6-v2 | 1 | READY | +------------------+---------+--------+
The top-level entry point for each of the LLM example pipelines is examples/llm/main.py. This script accepts a set of
options and a pipeline to run. For the purposes of this document, we'll focus on the vdb_upload pipeline option, which
incorporates various functionalities like handling RSS and filesystem sources, embedding configurations, and vector
database (VDB) settings.
When configuring the Morpheus Pipeline, especially for stages like the RSS source and the Vector Database Upload, it's important to balance responsiveness and performance.
-
RSS Source Stage: The RSS source stage is responsible for yielding webpage links for processing. A larger batch size at this stage can lead to decreased responsiveness, as the subsequent web scraper stage may take a considerable amount of time to retrieve and process all the items in each batch. To ensure a responsive experience for users, it's recommended to configure the RSS source stage with a relatively smaller batch size. This adjustment tends to have minimal impact on overall performance while significantly improving the time to process each batch of links.
-
Vector Database Upload Stage: At the other end of the pipeline, the Vector Database Upload stage has its own considerations. This stage experiences a significant transaction overhead. To mitigate this, it is advisable to configure this stage with the largest batch size possible. This approach helps in efficiently managing transaction overheads and improves the throughput of the pipeline, especially when dealing with large volumes of data.
Balancing these configurations ensures that the pipeline runs efficiently, with optimized responsiveness at the RSS source stage and improved throughput at the Vector Database Upload stage.
