langtrace weaviate integration cover art

In the era of LLMs, vector databases have become crucial in efficiently storing and querying high-dimensional data. Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database. To optimize and debug interactions with such a sophisticated system, tracing API calls is essential. This is where Langtrace, an SDK designed for tracing interactions with LLM (Large Language Models) and vector databases, comes into play.


In this blog, we’ll explore how to integrate Langtrace into a project using Weaviate. This integration will help us monitor, trace, and debug API calls, providing valuable insights into the behavior of our vector database operations.


  • Weaviate account with valid API key.
  • Langtrace project API key (can be either from Langtrace cloud or self-hosted)

Getting Started

For the sake of the demo, we will be using Weaviate Cloud with python SDK. If you wish to try different approaches for Weaviate, follow the official docs here.

Installing required dependencies

pip install weaviate-client langtrace-python-sdk

Create Collection

Copy the script on your local machine and export the following variables with actual values on your terminal

export LANGTRACE_API_KEY="<Langtrace Project API key>"

Uncomment the `create()` & `insert()` methods call and run the script to create an example collection


Query Weaviate

Once the collection is created, comment back the create & insert methods and uncomment query_data_near_text() to query the Weaviate data and observe traces. Run the script again.

You will now see traces being pushed to your Langtrace project!
