// Назначение: Система плагинов на основе Lua для расширения функциональности СУБД.
|
||
// Позволяет загружать Lua-скрипты как плагины, выполнять их в изолированном окружении,
|

// взаимодействовать с данными СУБД и логировать действия плагинов в общий лог-файл.
|
||
// УЛУЧШЕНИЯ: Sandbox с CPU/memory limits, Plugin Dependencies, Hot Reload (без fsnotify),
|
||
// Plugin Marketplace API, Пул Lua-состояний с ограничениями.
|
||
// ДОБАВЛЕНО: Поддержка кастомных движков хранения через Lua-плагины.
