Couchbase vs OpenSearch: Choosing the Right Vector Database for Your AI Apps
Blog post from Zilliz
Couchbase and OpenSearch are both open source tools that can be used for vector search in AI applications. Couchbase is a distributed, multi-model NoSQL document-oriented database that allows developers to store vector embeddings within JSON documents. It supports Full Text Search (FTS) and application-level computations for vector similarity searches. OpenSearch is an open source search and analytics platform with built-in vector search capabilities through its k-NN plugin, supporting both approximate and exact k-NN search methods. Both tools have their strengths and can be used depending on the specific use case, existing tech stack, and performance requirements.
