Qdrant Fundamentals
How many collections can I create?
You should create one collection and set it up for multitenancy. We believe that creating multiple collections is an anti-pattern, and we don't want to encourage it. Read more about Multitenancy.
Why are returned vectors null?
You can modify the scroll method to include the vectors by setting the with_vector parameter to True. If you're still seeing "vector": null in your point, it might be that the vector you're passing is not in the correct format, or there's an issue with how you're calling the upsert method.
How can I retrieve records based on filters only?
We do not allow search with vector=None. In Qdrant, "search" means similarity search for vectors. If you want to do query without vectors, we have specialized functions for it. for instance with the scroll method, you can retrieve the records based on filters only. Read more about scrolling here.
Does Qdrant support sparse vectors?
We have it in our roadmap, but currently, it’s not supported. We believe a hybrid search might be built with two separate tools combined. Read more about our approach to hybrid search.
Is there a way to recover the entire storage?
There is no endpoint for restoring the full storage? Instead, this can be done when starting Qdrant through the command line.
How do I upload a large number of vectors into a Qdrant collection?
You should use batches and load the vectors iteratively.
Can I only store quantized vectors and discard full precision vectors?
Qdrant needs to retain the original vectors for internal purposes.
When should I use Kubernetes vs. Docker containers?
To run a multi node setup we recommend Kubernetes, but for a single node you can run Docker. In general in production critical systems, we always advocate more nodes rather than one big one and activate replication for your collections. There are a lot of pros and cons of single installation versus Kubernetes and it very much depends on your use case.
Qdrant Cloud
Is it possible to scale down a Qdrant Cloud cluster?
In Qdrant Cloud scale downs are not possible at the moment.
Uploading snapshots via dashboard fails.
If you recover data from snapshot through the dashboard and uploading fails, then you might be experiencing a bug.
Please try to recover via the CLI.
