Does Casbin load all policies into memory at startup and what is the max size?

Hi everyone, I haven't read the source code yet. May I ask:
When Casbin's policy is stored in database, does it load all data into cache during project startup?
What's the maximum data size it can handle?

yes, load to memory, no hard limit, based on your hardware memory size, see docs: https://casbin.org/docs/performance#high-number-of-policy-rules
