NativeSQL will use inline rule resolution for core components
Resolved in Pega Version 8.5.1
After upgrade, nodes were going down with a heartbeat error. This was traced to issues with NativeSQL taking a very long time to generate queries due to the overhead in calling multiple complex functions to resolve rules. To correct this, updates have been made to resolve the standard set of functions used by core components inline in NativeSQL function resolution.
