03 Update a vector store

This workflow demonstrates how you can update an existing vector storewithout recreating embeddings for the entire knowledge base.

The workflow reads an existing vector store and imports new data, converting only the new content into embeddings. It then combines the original and new embeddings and writes them back to the vector store.

Import the saved vector store

Import new documents and create embeddings only for the new content

Extract existing embeddings into a table

Write the combined embeddings back to a vector store

🔁 No need to recreate embeddings – existing embeddings stored in the table column will be reused. Simply select the column with the embeddings in the node configuration.
