Thanks Michael Gibney , Shawn Heisey for pointing in the right direction. 1. Will there be any performance degrade if we use shards.preference? 2. How about leader election if we decided to use NRT + PULL ? TLOG has the advantage of participating in leader election correct? 3. NRT + TLOG is there any parameter which can reduce the TLOG replication time
