RUO	2b87e330b0	community: fix issue with nested field extraction in MongodbLoader (#22801 ) Description: This PR addresses an issue in the `MongodbLoader` where nested fields were not being correctly extracted. The loader now correctly handles nested fields specified in the `field_names` parameter. Issue: Fixes an issue where attempting to extract nested fields from MongoDB documents resulted in `KeyError`. Dependencies: No new dependencies are required for this change. Twitter handle: (Optional, your Twitter handle if you'd like a mention when the PR is announced) ### Changes 1. Field Name Parsing: - Added logic to parse nested field names and safely extract their values from the MongoDB documents. 2. Projection Construction: - Updated the projection dictionary to include nested fields correctly. 3. Field Extraction: - Updated the `aload` method to handle nested field extraction using a recursive approach to traverse the nested dictionaries. ### Example Usage Updated usage example to demonstrate how to specify nested fields in the `field_names` parameter: ```python loader = MongodbLoader( connection_string=MONGO_URI, db_name=MONGO_DB, collection_name=MONGO_COLLECTION, filter_criteria={"data.job.company.industry_name": "IT", "data.job.detail": { "$exists": True }}, field_names=[ "data.job.detail.id", "data.job.detail.position", "data.job.detail.intro", "data.job.detail.main_tasks", "data.job.detail.requirements", "data.job.detail.preferred_points", "data.job.detail.benefits", ], ) docs = loader.load() print(len(docs)) for doc in docs: print(doc.page_content) ``` ### Testing Tested with a MongoDB collection containing nested documents to ensure that the nested fields are correctly extracted and concatenated into a single page_content string. ### Note This change ensures backward compatibility for non-nested fields and improves functionality for nested field extraction. ### Output Sample ```python print(docs[:3]) ``` ```shell # output sample: [ Document( # Here in this example, page_content is the combined text from the fields below # "position", "intro", "main_tasks", "requirements", "preferred_points", "benefits" page_content='all combined contents from the requested fields in the document', metadata={'database': 'Your Database name', 'collection': 'Your Collection name'} ), ... ] ``` --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	3 months ago

Vwake04	0deb98ac0c	pinecone: Fix multiprocessing issue in PineconeVectorStore (#22571 ) Description: Currently, the `langchain_pinecone` library forces the `async_req` (asynchronous required) argument to Pinecone to `True`. This design choice causes problems when deploying to environments that do not support multiprocessing, such as AWS Lambda. In such environments, this restriction can prevent users from successfully using `langchain_pinecone`. This PR introduces a change that allows users to specify whether they want to use asynchronous requests by passing the `async_req` parameter through `kwargs`. By doing so, users can set `async_req=False` to utilize synchronous processing, making the library compatible with AWS Lambda and other environments that do not support multithreading. Issue: This PR does not address a specific issue number but aims to resolve compatibility issues with AWS Lambda by allowing synchronous processing. Dependencies:** None, that I'm aware of. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	3 months ago

In this patch, a new _aexit_history function which will'be called in async mode is added, and in turn aadd_messages will be called. In this patch, we use `afunc` attribute of a Runnable to check if the end listener should be run in async mode or not. - Issue: #22021, #22022 - Dependencies: N/A	3 months ago
