Vector index 26ai database

edited Oct 13, 2026 1:53AM in Database 4 comments

Hi Team,

From a DBA perspective regarding AI Vector Search:

Vector Indexing and Performance

What types of vector indexes are available in Oracle Database, such as HNSW and IVF, and what are the differences between them?

How do we decide based on the number of chunks, query performance, and memory usage?

Could you share an example of how to create the recommended vector index and how to validate its performance.

Thanks,

SGU
