Google Cloud Ai Platform V1 Client - Class IndexConfig (1.5.0)

Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class IndexConfig.

Configuration for vector indexing.

Generated from protobuf message google.cloud.aiplatform.v1.FeatureView.IndexConfig

Namespace

Google \ Cloud \ AIPlatform \ V1 \ FeatureView

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.

↳ tree_ah_config Google\Cloud\AIPlatform\V1\FeatureView\IndexConfig\TreeAHConfig

Optional. Configuration options for the tree-AH algorithm (Shallow tree + Asymmetric Hashing). Please refer to this paper for more details: https://arxiv.org/abs/1908.10396

↳ brute_force_config Google\Cloud\AIPlatform\V1\FeatureView\IndexConfig\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.

↳ embedding_column 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.

↳ filter_columns array

Optional. Columns of features that're used to filter vector search results.

↳ crowding_column 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.

↳ embedding_dimension int

Optional. The number of dimensions of the input embedding.

↳ distance_measure_type int

Optional. The distance measure used in nearest neighbor search.
