gtopt/aperture_data_cache.hpp file

Pre-loaded aperture scenario data for SDDP backward pass.

Loads all parquet files from the aperture_directory at construction time and provides fast lookup of flow/profile values by (class_name, element_name, scenario_uid, stage, block).

Internally uses a two-level structure: outer: unordered_map<(class, element), inner> inner: unordered_map<(scenario, stage, block), double>

This avoids storing redundant class/element strings per entry (only ~334 unique pairs vs 1.6M entries) and gives O(1) lookup.

Classes

class gtopt::ApertureDataCache

In-memory cache for aperture-specific schedule data.

struct gtopt::ApertureDataCache::ElementKey

Outer key: (class_name, element_name) — only ~hundreds of unique pairs.

struct gtopt::ApertureDataCache::ElementKeyHash

Hash for ElementKey using string hashes combined.

struct gtopt::ApertureDataCache::InnerKey

Inner key: pure integer triple — O(1) hashed lookup.

struct gtopt::ApertureDataCache::InnerKeyHash

Hash for InnerKey combining three integer hashes.
