In Pega7, from what I can find, HazelCast was used for inter-node communication for Decisioning. Other than Search, this was the only inter-node communication. There was another post saying there was a plan to use HazalCast for Locking (instead of using the database). So I want to confirm whether Locking or any other functionality is now using HazelCast in Pega 8.1. Thanks!
