/**
! * An read-only {@link IFusedView} that supports transactions and deletion
! * markers.
! * <p>
! * Processing deletion markers requires that the source(s) for an index
! * partition view are read in order from the most recent to the earliest
! * historical resource. The first entry for the key in any source is the value
! * that will be reported on a read. If the entry is deleted, then the read will
! * report that no entry exists for that key.
! * <p>
! * Note that deletion markers can exist in both historical journals and index
! * segments having data for the view. Deletion markers are expunged from index
! * segments only by a full compacting merge of all index segments having life
! * data for the partition.
! * <p>
! * Implementation note: the {@link IBatchBTree} operations are inherited from
! * the base class. Only non-batch read operations are overriden by this class.
! *
! * FIXME implement; support processing of delete markers (including handling of
! * the merge rule) - basically they have to be processed on read so that a
! * delete on the mutable btree overrides an historical value, and a deletion
! * marker in a more recent index segment overrides a deletion marker in an
! * earlier index segment. Deletion markers can exist in the both mutable btree
! * and in index segments that are not either a clean first eviction or a full
! * compacting merge (e.g., they can still exist in a compacting merge if there
! * are other index segments or btrees that are part of a partition but are not
! * partitipating in the compacting merge).
