> In CompactingMemStore both in BASIC and EAGER cases when snapshot is created the segments
are first removed from the pipeline then added to the snapshot. This is the opposite to what
is done in the DefaultMemStore where the snapshot is firstly created with the active segment
and only after the active segment is refreshed. This JIRA is about to reverse the order in
CompactingMemStore and to make all MemStores to behave the same.
