Creates and returns a new encrypted index based on the provided configuration.

std::unique_ptr<cyborg::EncryptedIndex> 
    CreateIndex(const std::string index_name,
                const std::array<uint8_t, 32>& index_key,
                const IndexConfig& index_config,
                const std::optional<size_t>& max_cache_size = 0);

Parameters

ParameterTypeDescription
index_namestd::stringName of the index to create (must be unique).
index_keystd::array<uint8_t, 32>32-byte encryption key for the index, used to secure index data.
index_configIndexConfigConfiguration for the index type (e.g., IVFFlat, IVFPQ).
max_cache_sizesize_t(Optional) Maximum size for the local cache (default is 0).

​
Returns

std::unique_ptr<cyborg::EncryptedIndex>: A pointer to the newly created index (EncryptedIndex).

Example Usage

#include "cyborgdb_core/client.hpp"
#include "cyborgdb_core/encrypted_index.hpp"
#include <array>

// ... Initialize the client ...

// Create a secure 32-byte key (example: all zeros)
std::array<uint8_t, 32> index_key = {0};

// Example vector dimensionality & number of lists
const size_t vector_dim = 1024;
const size_t num_lists = 128;

// Create an index configuration (e.g., using an IVFFlat configuration)
IndexIVFFlat index_config(vector_dim, num_lists, DistanceMetric::euclidean);

auto index = client.CreateIndex("my_index", index_key, index_config);
