Problem 1: Total consumption is much bigger than the other metric of Current Consumption, Where is the memory go ?

Problem 2: This two tablets are the top memory consumption, is it normal of DeltaMemStores? This two tablets are own the same table,one is Leader,another one is follower, and this will be many update scenarios on this table.

Note：There are many similar phenomena on our side: the memory cannot be reclaimed, and the only way is to restart the TabletServer. How should we do when this happen, or is the some way to reclaim memory manually ?
