When move a region form A to B, the > transformation of region state is PENDING_CLOSE => CLOSING => CLOSED => > PENDING_OPEN => OPENING => OPENED. When transform old region state to new > region state, it update the time stamp to current time. So we can't get the > overall transformation's duration of region in transition. Add a rit duration > to RegionState for accumulating this metric. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
