To address the issue of your RAG pipeline rebuilding the entire flow with each new query, consider implementing a caching mechanism for the HuggingFaceEmbeddingsComponent
. This involves specifying a cache_folder
in its configuration, allowing the component to store and reuse embeddings for subsequent queries, thus avoiding the need to recompute them. Here's a concise example on how to set this up:
from langchain_community.embeddings.huggingface import HuggingFaceEmbeddings
from langflow.interface.custom.custom_component import CustomComponent
hugging_face_embeddings_component = HuggingFaceEmbeddingsComponent().build(
cache_folder='/path/to/your/cache/folder', # Path to cache folder
encode_kwargs={}, # Optional: Additional encoding kwargs
model_kwargs={}, # Optional: Additional model kwargs
model_name='sentence-transformers/all-mpnet-base-v2', # Model name
multi_process=True # Optional: Enable multi-processing
)
By leveraging the cache_folder
, the component will check for existing embeddings before processing new queries, significantly reducing the computational load and speeding up the response time for your pipeline. This approach optimizes the use of document loaders, text splitters, and embeddings, ensuring efficient reuse across queries.

i have created a RAG pipeline using langflow, Where im using Huggingfacepipeline for llm, HuggingFaceEmbeddings for Embeddings and retrivalQA as chain and chat input and chat output for the same. So when i enter playground and send a query its builing the flow from start like documentloader, text splitters, embeddings.. and so on any suggestion will be of big help i will be attaching the image of my flow![Screenshot 2024-05-13 094923](https://github.com/langflow-ai/langflow/assets/129616972/9312394d-5a9d-4ffb-9996-63563ae6ed05)
