Vertex AI V1 API - Class Google::Cloud::AIPlatform::V1::RagVectorDbConfig::RagManagedDb::ANN (v1.27.0)

Reference documentation and code samples for the Vertex AI V1 API class Google::Cloud::AIPlatform::V1::RagVectorDbConfig::RagManagedDb::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.

Methods

#leaf_count

def leaf_count() -> ::Integer
Returns
  • (::Integer) — 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.

#leaf_count=

def leaf_count=(value) -> ::Integer
Parameter
  • value (::Integer) — 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.

Returns
  • (::Integer) — 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.

#tree_depth

def tree_depth() -> ::Integer
Returns
  • (::Integer) — 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.

#tree_depth=

def tree_depth=(value) -> ::Integer
Parameter

    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.
