Alex, thanks for reply. The query is fairly simple, colA =? colA is String. For 1 server 1 client scenario, they are the same server. For 2 server 1 client scenario, one server and client are on one server, the other server node is on another server. Working on a simplified code to reproduce the problem to share with you
