V$VECTOR_GRAPH_INDEX_CHKPT

V$VECTOR_GRAPH_INDEX_CHKPT displays diagnostic information about In-Memory Neighbor Graph vector index disk checkpoints.

This view is populated only on Oracle Autonomous AI Database Serverless (ADB-S).

Column	Datatype	Description
`INDEX_OBJN`	`NUMBER`	Index object number
`CHECKPOINT_ID`	`NUMBER`	Unique identifier for the checkpoint
`CHECKPOINT_SCN`	`NUMBER`	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 `BLOB`s into which the graph checkpoint is divided.
`CHECKPOINT_SIZE`	`NUMBER`	Total size of the checkpoint, including serialized `BLOB`s 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
