vectorIndexes

The vector indexes, if any, on the table. Each element is composed of:

• IndexName - The name of the vector index.

• IndexStatus - The current status of the vector index: CREATING, ACTIVE, or DELETING.

• Backfilling - Specifies whether the index is currently backfilling. During backfill, SearchVectors operations might return incomplete results.

• VectorAttribute - The attribute that contains vector embeddings.

• Dimensions - The number of dimensions in each vector.

• DistanceFunction - The distance function used to calculate similarity (COSINE, EUCLIDEAN, or DOT_PRODUCT).

• SearchSchema - The partition key and inline filter attributes for the vector index.

• Projection - Specifies attributes that are copied (projected) from the table into the vector index.

• IndexArn - The Amazon Resource Name (ARN) that uniquely identifies the index.

• IndexSizeBytes - The total size of the vector index, in bytes. Amazon DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

• ItemCount - The number of items indexed in the vector index. Amazon DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
