#include <userver/dynamic_config/snapshot.hpp>
The shared snapshot of dynamic configs. Cheap to copy, even cheaper to move. Thread safe, not updated with new dynamic config values in background (it's a snapshot!).
When a config update comes in via new DocsMap
, configs of all the registered types are constructed and stored in Config
. After that the DocsMap
is dropped.
Config types are automatically registered if they are used somewhere in the program.
