Vector Index and Hybrid Vector Index Views

These views allow you to query tables related to vector indexes and hybrid vector indexes.

• V$VECTOR_INDEX This fixed view provides diagnostic information about vector indexes and is available with Autonomous AI Database Serverless (ADB-S).

• V$VECTOR_INDEX_INST_MAP This fixed view provides cluster mapping and distribution metadata for distributed HNSW vector indexes.

• V$VECTOR_GRAPH_INDEX This fixed view provides diagnostic information about In-Memory Neighbor Graph vector indexes and is available with Autonomous AI Database Serverless (ADB-S).

• V$VECTOR_GRAPH_INDEX_CHKPT This fixed view provides diagnostic information about In-Memory Neighbor Graph vector index disk checkpoints and is available with Autonomous AI Database Serverless (ADB-S).

• V$VECTOR_GRAPH_INDEX_SNAPSHOT This fixed view provides diagnostic information about In-Memory Neighbor Graph vector index snapshots and is available with Autonomous AI Database Serverless (ADB-S).

• V$VECTOR_PARTITIONS_INDEX This fixed view provides diagnostic information about Inverted File Flat indexes and is available with Autonomous AI Database Serverless (ADB-S).

• <index name>$VECTORS This dictionary table provides information about the vector index part of a hybrid vector index, showing the contents of the $VR table with row ids, chunks, and embeddings.

• VECSYS.VECTOR$INDEX This catalog table contains detailed information about vector indexes. This table is not available when using Autonomous AI Database Serverless (ADB-S) or Dedicated (ADB-D). Oracle recommends using the fixed view, V$VECTOR_INDEX, instead.

• VECSYS.VECTOR$INDEX$CHECKPOINTS This catalog table provides detailed information about Hierarchical Navigable Small World (HNSW) full checkpoints at the database level. This table is not available when using Autonomous AI Database Serverless (ADB-S) or Dedicated (ADB-D). Oracle recommends using the fixed view, V$VECTOR_GRAPH_INDEX_CHKPT, instead.
