DISABLE_CHECKPOINT

Use the DISABLE_CHECKPOINT procedure to disable the Checkpoint feature for a given Hierarchical Navigable Small World (HNSW) index user and HNSW index name. This operation purges all older checkpoints for the HNSW index. It also disables the creation of future checkpoints as part of the HNSW graph refresh.

Syntax

DBMS_VECTOR.DISABLE_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 disable the Checkpoint feature.

The INDEX_NAME clause is optional. If you do not specify the index name, then this procedure disables the Checkpoint feature for all HNSW vector indexes under the given user.

Examples

  • Using both the index name and index user:

    DBMS_VECTOR.DISABLE_CHECKPOINT('VECTOR_USER','VIDX1');

  • Using only the index user:

    DBMS_VECTOR.DISABLE_CHECKPOINT('VECTOR_USER');
