Reference documentation and code samples for the Vertex AI v1 API class RagVectorDbConfig.Types.RagManagedDb.Types.ANN.

Config for ANN search.

RagManagedDb uses a tree-based structure to partition data and facilitate faster searches. As a tradeoff, it requires longer indexing time and manual triggering of index rebuild via the ImportRagFiles and UpdateRagCorpus API.

Properties

LeafCount

public int LeafCount { get; set; }

Number of leaf nodes in the tree-based structure. Each leaf node contains groups of closely related vectors along with their corresponding centroid.

Recommended value is 10 * sqrt(num of RagFiles in your RagCorpus).

Default value is 500.

Property Value
Type Description
int

TreeDepth

public int TreeDepth { get; set; }

The depth of the tree-based structure. Only depth values of 2 and 3 are supported.

Recommended value is 2 if you have if you have O(10K) files in the RagCorpus and set this to 3 if more than that.

Default value is 2.
