From 04b9065f0829c57195fddcef8b231fbc946c165e Mon Sep 17 00:00:00 2001 From: PVBLIC Foundation Date: Thu, 8 May 2025 15:53:30 -0700 Subject: [PATCH] Update pinecone.py Now supports batched insert, upsert, and delete operations using a default batch size of 100, reducing API strain and improving throughput. All blocking calls to the Pinecone API are wrapped in asyncio.to_thread(...), ensuring async safety and preventing event loop blocking. The implementation includes zero-vector handling for efficient metadata-only queries, normalized cosine distance scores for accurate ranking, and protections against empty input operations. Logs for batch durations have been streamlined to minimize noise, while preserving key info-level success logs. --- .../retrieval/vector/dbs/pinecone.py | 147 ++++++++++++------ 1 file changed, 97 insertions(+), 50 deletions(-) diff --git a/backend/open_webui/retrieval/vector/dbs/pinecone.py b/backend/open_webui/retrieval/vector/dbs/pinecone.py index bc9bd8bc3..a809f1d2c 100644 --- a/backend/open_webui/retrieval/vector/dbs/pinecone.py +++ b/backend/open_webui/retrieval/vector/dbs/pinecone.py @@ -1,7 +1,49 @@ from typing import Optional, List, Dict, Any, Union import logging +import asyncio from pinecone import Pinecone, ServerlessSpec +# Helper for building consistent metadata +def build_metadata( + *, + source: str, + type_: str, + user_id: str, + chat_id: Optional[str] = None, + filename: Optional[str] = None, + text: Optional[str] = None, + topic: Optional[str] = None, + model: Optional[str] = None, + vector_dim: Optional[int] = None, + extra: Optional[Dict[str, Any]] = None, + collection_name: Optional[str] = None, +) -> Dict[str, Any]: + from datetime import datetime + + metadata = { + "source": source, + "type": type_, + "user_id": user_id, + "timestamp": datetime.utcnow().isoformat() + "Z", + } + if chat_id: + metadata["chat_id"] = chat_id + if filename: + metadata["filename"] = filename + if text: + metadata["text"] = text + if topic: + metadata["topic"] = topic + if model: + metadata["model"] = model + if vector_dim: + metadata["vector_dim"] = vector_dim + if collection_name: + metadata["collection_name"] = collection_name + if extra: + metadata.update(extra) + return metadata + from open_webui.retrieval.vector.main import ( VectorDBBase, VectorItem, @@ -27,7 +69,8 @@ log.setLevel(SRC_LOG_LEVELS["RAG"]) class PineconeClient(VectorDBBase): def __init__(self): -
