The Process Commander engine maintains an in-memory table that allows the system to rapidly identify compiled Java CLASS files that correspond to compiled and assembled rules (such as activities, functions, and stream rules).

Don't confuse the rules assembly cache with the rules cache, which contains copies of rules recently accessed or recently updated by developers, and can include any rule types, not just those that are compiled into Java.

In older versions, this cache was known as the first-use-assembly or fua cache.
