Typed relationship

milvus alternative oceanbaseBoth OceanBase and Milvus serve as vector databases for scalable vector ANN search, addressing similar use cases but from different design perspectives.

Choose milvus if…

  • milvus is primarily Go; oceanbase is C++.
  • Milvus is designed to be self-hosted and can be deployed in a cloud-native environment.
  • Pricing: Milvus is free to use under the Apache-2.0 license, but additional services or support may come at a cost..
  • Requirements: Min 4 GB RAM; Requires Docker; Third-party dependencies must be installed before using Milvus.; Milvus is built with Go and requires a Go environment to run..
  • Both OceanBase and Milvus serve as vector databases for scalable vector ANN search, addressing similar use cases but from different design perspectives.
  • Tags unique to milvus: anns, diskann, distributed, embedding-database.
  • Also covers Data & Retrieval.
  • milvus ships Docker support for self-hosted deployment.
  • When you need a high-performance vector database that supports scalable approximate nearest neighbor search.

When NOT to use milvus

  • If your project does not require vector similarity search or approximate nearest neighbor search capabilities.
  • When the project is not cloud-native and does not benefit from cloud-native optimizations.
  • If the project's requirements are better met by a non-vector database or a different type of database.
  • When the specific indexing techniques and performance characteristics of Milvus do not align with your project's needs.

Choose oceanbase if…

  • oceanbase is primarily C++; milvus is Go.
  • Pricing: Not Provided.
  • Requirements: Dependent on specific workload and scale, but optimized for distributed environments..
  • Both OceanBase and Milvus serve as vector databases for scalable vector ANN search, addressing similar use cases but from different design perspectives.
  • Tags unique to oceanbase: analytics, database, distributed-database, fulltext-search.
  • The Fastest HTAP: Use OceanBase when your application requires high-speed handling of both online transaction processing (OLTP) and online analytical processing (OLAP) tasks.

When NOT to use oceanbase

  • Limited Support for Non-C++ Ecosystems: Avoid OceanBase if your development environment heavily relies on languages other than C++, as it's predominantly built with C++.
  • Mature Alternatives in Non-HTAP Scenarios: Do not choose OceanBase if your project requires only traditional OLTP or OLAP services, since it might overcomplicate your setup without necessary benefits.
