ENABLE_CHECKPOINT
Use the ENABLE_CHECKPOINT
procedure to enable the Checkpoint feature for a given Hierarchical Navigable Small World (HNSW) index user and HNSW index name.
Note:
-
This procedure only allows the index to create checkpoints. The checkpoint is created as part of the next HNSW graph refresh.
-
By default, HNSW checkpointing is enabled. If required, you can disable it using the
DBMS_VECTOR.DISABLE_CHECKPOINT
procedure.
Syntax
DBMS_VECTOR.ENABLE_CHECKPOINT('INDEX_USER',['INDEX_NAME']);
INDEX_USER
Specify the user name of the HNSW vector index owner.
INDEX_NAME
Specify the name of the HNSW vector index for which you want to enable the Checkpoint feature.
The INDEX_NAME
clause is optional. If you do not specify the index name, then this procedure enables the Checkpoint feature for all HNSW vector indexes under the given user.
Examples
-
Using both the index name and index user:
DBMS_VECTOR.ENABLE_CHECKPOINT('VECTOR_USER','VIDX1');
-
Using only the index user:
DBMS_VECTOR.ENABLE_CHECKPOINT('VECTOR_USER');
