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

Column Name	Data Type	Description
OWNER	VARCHAR(129)	User name of the vector index owner
INDEX_NAME	VARCHAR(129)	Name of the vector index
PARTITION_NAME	VARCHAR(129)	Object partition name (set to NULL for non-partitioned objects)
INDEX_ORGANIZATION	VARCHAR(129)	The vector index organization. The value can be one of the following: NEIGHBOR PARTITIONS INMEMORY NEIGHBOR GRAPH
INDEX_OBJN	NUMBER	Index object number
ALLOCATED_BYTES	NUMBER	Total amount of memory allocated to this vector index, in bytes. When the vector index is an IVF index, the value is 0.
USED_BYTES	NUMBER	Total amount of memory currently used by the vector index, in bytes. When the vector index is an IVF index, the value is 0.
NUM_VECTORS	NUMBER	The number of vectors currently indexed in the main-memory storage of the index as of the latest snapshot
NUM_REPOP	NUMBER	Number of times this index has been repopulated
INDEX_USED_COUNT	NUMBER	Number of times this vector index has been used by queries
DISTANCE_TYPE	VARCHAR2(129)	Possible distance values: EUCLIDEAN EUCLIDEAN_SQUARED COSINE DOT MANHATTAN HAMMING
INDEX_DIMENSIONS	NUMBER	Number of dimensions of the indexed vector
INDEX_DIM_TYPE	VARCHAR2(129)	Type of the dimensions of the index vector. Possible values: FLOAT16 FLOAT32 FLOAT64 INT8
DEFAULT_ACCURACY	NUMBER	The accuracy to achieve when performing approximate search on this vector index if a target query accuracy is not provided
CON_ID	NUMBER	The ID of the container to which the data pertains. Possible values include the following: 0: This value is used for rows containing data that pertain to the entire multitenant container database (CDB). This value is also used for rows in non-CDBs. 1: This value is used for rows containing data that pertain to only the root. n: Where n is the applicable container ID for the rows containing data.
