Pgvector vs. Zilliz Cloud
Compare Pgvector vs. Zilliz Cloud by the following set of capabilities. We want you to choose the best database for you, even if it’s not us.
Pgvector vs. Zilliz Cloud on Scalability
Yes. pgvector enables separation of storage and compute by allowing you to store your application data on one database while storing vectors, lookup values, and filter values on a separate database.
Yes.
Yes. At the component level (which provides more fine-grained scalability)
Dynamic segment placement
pgvector scalability
You can use a solution like YugaByteDB to extend the capabilities of Postgres for distributed environments.
Zilliz Cloud
Zilliz Cloud is a managed vector database service powered by Milvus. Its cloud-native architecture dynamically scales to 10B+ vectors, maintaining high performance and cost-efficiency without the need for new clusters or data sharding.
Pgvector vs. Zilliz Cloud 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. Sparse & Dense Vectors and Scalar filtering.
Yes, Hybrid sparse and dense search, hybrid keyword and vector search, hybrid vector search and scalar filtering, multimodal search
Yes.
