# segment_n PUT A, segment_x DELETE A
# After the "DELETE A" in segment_x the shadow index will contain "A -> [n]".
# .delete() is updating this index, it is persisted into "hints" file and is later used by .compact_segments().
# We need the entries in the shadow_index to not accidentally drop the "DELETE A" when we compact segment_x
# only (and we do not compact segment_n), because DELETE A is still needed then because PUT A will be still
# there. Otherwise chunk A would reappear although it was previously deleted.
