Multithreading

In multi-threaded code, use Casbin’s synchronized enforcer so one enforcer can be shared safely across threads: SyncedEnforcer (Go), enforcer_synced.cpp (C++).

The synced enforcer can also auto-reload policy: call StartAutoLoadPolicy() to poll the policy source and reload when it changes; call StopAutoLoadPolicy() to stop.

For running several instances, caching and keeping policy in sync, see Production Deployment.
