Qdrant

Overview

The node provides an interface to interact with Qdrant, a vector search engine and database. Specifically, the "Get Collection" operation under the "Collection" resource allows users to retrieve details about a specific collection stored in Qdrant. This is useful when you want to fetch metadata or configuration of a collection before performing further operations like searching vectors or managing points within that collection.

Practical examples include:

• Retrieving collection information to verify its existence and settings.
• Using collection details to dynamically configure subsequent nodes in a workflow.
• Auditing collections programmatically as part of data management processes.

Properties

Output

The node outputs JSON data representing the details of the requested collection. This typically includes metadata such as collection configuration, status, and other relevant properties defined by Qdrant for that collection.

No binary data output is involved in this operation.

Dependencies

• Requires an API key credential for authenticating requests to the Qdrant REST API.
• The base URL for the Qdrant instance must be configured in the node credentials.
• The node depends on Qdrant's REST API being accessible and properly configured.

Troubleshooting

• Common issues:

  • Invalid or missing collection name will result in errors or empty responses.
  • Network connectivity problems or incorrect base URL can cause request failures.
  • Insufficient permissions or invalid API credentials will lead to authentication errors.

• Error messages and resolutions:

  • "Collection not found": Verify the collection name is correct and exists in Qdrant.
  • Authentication errors: Check that the API key credential is valid and has necessary permissions.
  • Network errors: Ensure the Qdrant server URL is reachable from n8n and no firewall blocks exist.
