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 Database Serverless (ADB-S).

Column Name	Data Type	Description
INDEX_OBJN	NUMBER	Index object number
CHECKPOINT_ID	NUMBER	Unique identifier for the checkpoint
CHECKPOINT_SCN	NUMBER	The SCN at which the checkpoint was created
CHECKPOINT_TYPE	NUMBER	Indicates whether the checkpoint is a full checkpoint or incremental checkpoint. The value of this column is always 1, which indicates a full checkpoint.
VERSION_NUMBER	NUMBER	Version number for the checkpoint
TABLESPACE_NUMBER	NUMBER	TSN for the tablespace storing the checkpoint
NUM_VECTORS	NUMBER	Number of vectors currently present in the checkpoint
NUM_DELETES	NUMBER	Number of vertices marked as deleted in the checkpoint graph
MAX_VERTEX_ID	NUMBER	Maximum vertex ID for the checkpoint
NUM_LAYERS	NUMBER	Number of graph layers in the checkpoint
NUM_COMPONENTS	NUMBER	Number of subcomponents in the multi-layered graph checkpoint. This value can be used to track the multiple BLOBs into which the graph checkpoint is divided.
CHECKPOINT_SIZE	NUMBER	Total size of the checkpoint, including serialized BLOBs for each graph layer (in bytes)
CON_ID	NUMBER	The ID of the container to which the data pertains. Possible values include: 0: This value is used for rows containing data that pertain to the entire 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
