Properties

bruteForceConfig → FeatureView_VectorSearchConfig_BruteForceConfig?
Optional. Configuration options for using brute force search, which simply implements the standard linear search in the database for each query. It is primarily meant for benchmarking and to generate the ground truth for approximate search.
final
crowdingColumn → String
Optional. Column of crowding. This column contains crowding attribute which is a constraint on a neighbor list produced by FeatureOnlineStoreService.SearchNearestEntities to diversify search results. If NearestNeighborQuery.per_crowding_attribute_neighbor_count is set to K in SearchNearestEntitiesRequest, it's guaranteed that no more than K entities of the same crowding attribute are returned in the response.
final
distanceMeasureType → FeatureView_VectorSearchConfig_DistanceMeasureType
Optional. The distance measure used in nearest neighbor search.
final
embeddingColumn → String
Optional. Column of embedding. This column contains the source data to create index for vector search. embedding_column must be set when using vector search.
final
embeddingDimension → int?
Optional. The number of dimensions of the input embedding.
final
filterColumns → List<String>
Optional. Columns of features that're used to filter vector search results.
final
hashCode → int
The hash code for this object.

qualifiedName → String
The fully qualified name of this message, i.e., google.protobuf.Duration or google.rpc.ErrorInfo.

runtimeType → Type
A representation of the runtime type of the object.

treeAhConfig → FeatureView_VectorSearchConfig_TreeAhconfig?
Optional. Configuration options for the tree-AH algorithm (Shallow tree
