Как из идеи Shared Memory кэша родился LensDB

1. пока что нет ttl-реализации, но в дальнейшем, думаю, добавлю

2. контроль использования памяти/диска на уровне конфигурации есть частично (max_memory), но жёстких ограничений нет, это контролируется на уровне окружения (например, kubernetes)

Как из идеи Shared Memory кэша родился LensDB

ну, проект находится в стадии разработки, в будущем он будет в разы удобнее и лучше, особенно для масштабных проектов или где нужно сохранять оптимизацию = работоспособность

это при альфе версии так, в будущем я думаю еще ускорить и оптимизировать
