Milvus vs. MongoDB Atlas
Compare Milvus 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.
Milvus vs. MongoDB Atlas on Scalability
Yes. Atlas introduced search nodes, providing dedicated infrastructure for Atlas search and vector search workloads.
Yes. At the component level (which provides more fine-grained scalability).
Dynamic segment placement
Yes. Atlas can dynamically balance the data between shards via range migrations.
Milvus scalability
Regarding scalability, Milvus uses worker nodes for each type of action (components to handle connections, data nodes to handle ingestion, index nodes to index, and query nodes to search). Each node has its own assigned CPU and memory resources. Milvus can dynamically allocate new nodes to an action group, speeding up operations or reducing the number of nodes, thus freeing resources for other actions. Dynamically allocating nodes allows for easier scaling and resource planning and guarantees latency and throughput.
Milvus 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.
Yes (DiskANN)
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.

Milvus functionality
- Milvus supports multiple in-memory indexes and table-level partitions results in the high performance required for real-time information retrieval systems.
- RBAC support is a requirement for enterprise-grade applications.
- In regards to partitions, by limiting searches to one or several subsets of the database, partitions can provide a more efficient way to filter data compared to static sharding, which can introduce bottlenecks and require re-sharding as data grows beyond server capacity. Partitions are a great way to manage your data by grouping it into subsets based on categories or time ranges. This can help you to easily filter and search through large amounts of data, without having to search through the entire database every time.
- No single Index type can fit all use cases since each use case will have different tradeoffs With more index types supported, you have more flexibility to find the balance between accuracy, performance and cost.
MongoDB (Atlas Vector Search)
Atlas has support for vector embeddings that are less than or equal to 2048 dimensions.
Milvus 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
