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

| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ tree_depth |
int
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. |
↳ leaf_count |
int
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. |
getTreeDepth
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.
