​
Prerequisites

Before integrating Langtrace with Qdrant, ensure you have the following:

  • Qdrant client library installed
  • Langtrace Python SDK installed

​
Installation

If you haven’t already installed the required libraries, you can do so using pip:

Python
pip install qdrant-client langtrace-python-sdk

​
Basic Setup

To start using Langtrace with Qdrant, you need to initialize both clients:

Python
from langtrace_python_sdk import langtrace, with_langtrace_root_span
from qdrant_client import QdrantClient

# Initialize Qdrant client
qdrant_client = QdrantClient("localhost", port=6333)

# Initialize Langtrace
langtrace.init(api_key='your_langtrace_api_key_here')

​
Tracing Qdrant Operations

Langtrace allows you to trace various Qdrant operations. Here are some common operations and how to trace them:

​
Adding Points to a Collection

Python
@with_langtrace_root_span("add_points")
def add_points_to_collection(collection_name, points):
    qdrant_client.upsert(
        collection_name=collection_name,
        points=points
    )

​
Searching in a Collection

Python
@with_langtrace_root_span("search")
def search_collection(collection_name, query_vector, limit=10):
    return qdrant_client.search(
        collection_name=collection_name,
        query_vector=query_vector,
        limit=limit
    )

​
Creating a Collection

Python
@with_langtrace_root_span("create_collection")
def create_collection(collection_name, vector_size):
    qdrant_client.recreate_collection(
        collection_name=collection_name,
        vectors_config=models.VectorParams(size=vector_size, distance=models.Distance.COSINE)
    )

​
Best Practices

  1. Meaningful Span Names: Choose descriptive names for your spans to easily identify operations in the Langtrace dashboard.

  2. Error Handling: Wrap your Qdrant operations in try-except blocks to capture and trace errors:

Python
   @with_langtrace_root_span("qdrant_operation")
   def qdrant_operation():
       try:
           # Qdrant operation here
           pass
       except Exception as e:
           add_attribute_to_current_span("error", str(e))
           raise
  1. Performance Monitoring: Use Langtrace to monitor the performance of your Qdrant operations over time. This can help you identify slow queries or other bottlenecks in your application.

​
Troubleshooting

If you encounter issues with Langtrace and Qdrant integration, consider the following:

  1. Check Connectivity: Ensure that both Qdrant and Langtrace servers are accessible from your application.

  2. Verify API Keys: Double-check that you’re using the correct Langtrace API key.

  3. Update Libraries: Ensure you’re using the latest versions of both the Qdrant client and Langtrace SDK.

For more assistance, refer to the Langtrace documentation or Qdrant documentation, or reach out to the respective support channels.
