Description
When a non in place update occurs, the update implementation extracts all index keys for all index fields from both the old and updated versions of the document. For a large number of index keys this can be expensive. And it may not always be necessary if there are cases where it can be determined from the update mod spec that a given index's key set will not be modified.
