Qdrant vs. MongoDB Atlas
Compare Qdrant vs. MongoDB Atlas by the following set of capabilities. We want you to choose the best database for you, even if it’s not us.
Qdrant vs. MongoDB Atlas on Scalability
Yes. Atlas introduced search nodes, providing dedicated infrastructure for Atlas search and vector search workloads.
No. Only scale at the server level.
Static sharding
Yes. Atlas can dynamically balance the data between shards via range migrations.
Qdrant scalability
With static sharding, if your data grows beyond the capacity of your server, you will need to add more machines to the cluster and re-shard all of your data. This can be a time-consuming and complex process. Additionally, imbalanced shards can introduce bottlenecks and reduce the efficiency of your system.
Qdrant vs. MongoDB Atlas on Functionality
Performance is the biggest challenge with vector databases as the number of unstructured data elements stored in a vector database grows into hundreds of millions or billions, and horizontal scaling across multiple nodes becomes paramount.
Furthermore, differences in insert rate, query rate, and underlying hardware may result in different application needs, making overall system tunability a mandatory feature for vector databases.
No. Authentication only
Yes. Sparse & Dense Vectors and Scalar filtering.
Yes - Pre-filtering using an MQL match experssion that compares an indexed field with boolean, number, or string.
No. MongoDB organizes data into databases and collections, but it does not have a hierarchical structure like sub-collections within collections.

Qdrant functionality
Qdrant uses three types of indexes to power the database. The three indexes are a Payload index, similar to an index in a conventional document-oriented database, a Full-text index for string payload, and a vector index. Their hybrid search approach is a combination of vector search with attribute filtering.
MongoDB (Atlas Vector Search)
Atlas has support for vector embeddings that are less than or equal to 2048 dimensions.
Qdrant vs. MongoDB Atlas on Purpose-built
What’s your vector database for?
A vector database is a fully managed solution for storing, indexing, and searching across a massive dataset of unstructured data that leverages the power of embeddings from machine learning models. A vector database should have the following features:
- Scalability and tunability
- Multi-tenancy and data isolation
- A complete suite of APIs
- An intuitive user interface/administrative console
