Reopening of intel#275 for developer branch --------- Co-authored-by: Dmitry Razdoburdin <drazdobu@intel.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
This PR introduce native serialization for DynamicFlat index. Main changes are: 1. `auto_dynamic_assemble` now accepts lazy loader. That is mandatory for buffer-free deserialization. 2. new class `Deserializer' is introduced. It is responsible for conditional reading of overhead data (like names of temporary files) in case of legacy models. 3. `IDTranslator` is refactored to cover save and load to/from stream. --------- Co-authored-by: Dmitry Razdoburdin <drazdobu@intel.com>
This PR introduce native serialization for `Vamana` index. Main changes are: 1. New overload of `svs::index::vamana::auto_assemble` required for direct deserialization accepts lazy loaders and call them in a flexible order to cover legacy serilized models. 2. `save_table` method is renamed to `metadata` to avoid confusions, as far as it doesn't save anything. 3. Some minor refactoring to streamline the logic. 4. Serialization for `MutableVamana` is also implemented to avoid compilation errors. Deserialization and related tests for `MutableVamana` are expected later. --------- Co-authored-by: Dmitry Razdoburdin <drazdobu@intel.com> Co-authored-by: Rafik Saliev <rafik.f.saliev@intel.com>
This PR introduce native serialization for `MutableVamana` index. Main changes are: 1. New overload of svs::index::vamana::auto_dynamic_assemble required for direct deserialization accepts lazy loaders and call them in a flexible order to cover legacy serialized models. 2. The test file tests/svs/index/vamana/dynamic_index.cpp is returned to the test build, as far as it is the right place for serialization tests. 3. Some minor refactoring to streamline the logic.

This PR diverse deserialization paths for newly serialized models with a legacy ones. The main changes are: 1. Legacy models are now deserialized with intermediate files, as it was done before. 2. Native deserialization path is cleaned, as far as we don't need support of legacy models for this path. --------- Co-authored-by: Dmitry Razdoburdin <drazdobu@intel.com>
This PR introduce native serialization for IVF index. Main changes are: 1. New overload of svs::index::ivf::load_ivf_index accpting istream is introduced. 2. Added related tests. 3. save(std::ostream&) method for DynamicIVF is just a placeholder for now. Real implementation is expected later. Co-authored-by: Dmitry Razdoburdin <drazdobu@intel.com>
