You are implementing AI Vector Search in Oracle Database 23ai. Which data type is mandatory for storing vector embeddings?
Oracle Database 23ai introduces the VECTOR data type specifically for storing vector embeddings, and it is mandatory for AI Vector Search because it defines the dimensions and numeric format needed for distance calculations. Other data types such as BLOB or CLOB can store binary …Read full explanation
When using Blockchain Tables, what is the default behavior for rows that have reached their 'no drop' period?
In Oracle Blockchain Tables, rows are immutable and cannot be updated or deleted until the 'no drop' period expires. After the no-drop period, the default behavior is that rows remain immutable until explicitly deleted by a user—they are not automatically purged. This preserves t…Read full explanation
You have a vector index and notice search performance is slow. Which index type should you use to optimize similarity search?
HNSW (Hierarchical Navigable Small World) is a graph-based index specifically designed for approximate nearest neighbor search in high-dimensional vector spaces. It provides fast and accurate similarity search by building a multi-layer graph structure. Other index types like inve…Read full explanation
