      Description

      This includes the following steps, which must be committed together:

      • Add lazy BSON shredding.
      • Change DocumentStorageIterator to accommodate the above lazy strategy.
      • Necessary changes in ValueElement to accommodate the above. In ValueElement we will have to keep track of whether the element represents an insert, update, delete, or cached field lookup.
