Qdrant

Overview

This node integrates with Qdrant, a vector search engine and database, to retrieve a specific point from a collection. The "Retrieve Point" operation fetches detailed information about a single point identified by its unique ID within a specified collection.

Common scenarios for this node include:

• Fetching metadata or payload associated with a particular vector point.
• Retrieving a point's data for further processing or analysis in workflows.
• Validating the existence or content of a point before performing updates or deletions.

Practical example:

• In a recommendation system, after identifying a relevant vector point ID, use this node to get the full details of that point (e.g., user profile or product info) to personalize content.

Properties

Output

The node outputs JSON data representing the retrieved point. This typically includes:

• The point's unique ID.
• Its vector data.
• Associated payload (metadata).
• Any additional attributes stored with the point.

No binary data output is produced by this operation.

Dependencies

• Requires an API key credential for authenticating with the Qdrant REST API.
• Needs the base URL of the Qdrant instance configured in the credentials.
• The node sends HTTP requests to the Qdrant API endpoint to perform operations.

Troubleshooting

• Point Not Found: If the specified point ID does not exist in the collection, the node may return an error or empty result. Verify the point ID and collection name are correct.
• Invalid Collection Name: Using a non-existent collection name will cause errors. Use the list mode to select valid collections or ensure the manual name matches exactly.
• Authentication Errors: Ensure the API key and base URL credentials are correctly set up and have sufficient permissions.
• Network Issues: Connectivity problems to the Qdrant server will cause request failures; check network access and server status.
