-
No need use LoadPolicy and SavePolicy.
Auto save is supported now. SavePolicy is overwrite by just batch putItems without recreate table and adapter.loadPolicy after. Cause dynamodb recreate table has latency, and adapter.loadPolicy is repeat not reload when call it multi times. which is unreliable.

About policy unique
ID is hash key which value is unique by use md5(policy)
-
About RemoveFilteredPolicy
RemoveFilteredPolicy is implement by getAllItems and then filter items to delete. This may has latency when data is so big. Use as appropriate.
