I’m having trouble figuring out how to assign unique IDs to Qdrant points when using n8n. The Qdrant docs say that points with the same ID will be replaced, which is exactly what I need. But I can’t find a way to set the point ID in n8n.
I tried putting the ID in the metadata, but that’s not the same as the actual point ID. Now I’m ending up with duplicate documents every time I insert the same data.
Does anyone know how to properly set the point ID in n8n when working with Qdrant? I really need to avoid these duplicates. Thanks for any help!
I’ve faced similar challenges before. In n8n, a reliable solution is to incorporate a Function node to generate unique IDs before the data reaches Qdrant. You can write a custom script in the Function node to combine the timestamp and specific data fields to create a unique ID. Afterwards, map this custom field to the ‘id’ parameter in your Qdrant node. This approach gives full control over the ID generation process and helps prevent duplicate entries.
hey Luna23, i had the same issue! try using the ‘Set’ node in n8n to create a unique id field before sending to Qdrant. u can use a combination of existing fields or smthing like timestamp+random string. then map that field to the ‘id’ parameter in the Qdrant node. hope this helps!
I’ve been working with Qdrant and n8n for a while now, and I can share what worked for me. Instead of relying on metadata or trying to generate IDs within n8n, I found it more reliable to use Qdrant’s built-in ID generation. In the Qdrant node settings, there’s an option to leave the ID field blank. When you do this, Qdrant automatically assigns a unique ID to each point.
If you need to update existing points, you can query Qdrant first to get the IDs of matching points, then use those IDs in your update operation. This approach has helped me avoid duplicates and maintain data integrity.
For cases where you absolutely need custom IDs, consider using a Function node in n8n to generate and assign IDs based on your specific requirements before sending data to Qdrant. This gives you full control over the ID generation process.
