SetOptions

An options object that configures the behavior of set() calls. By providing one of the SetOptions objects returned by merge(), mergeFields(String...) and mergeFieldPaths(List), the set() calls in DocumentReference, WriteBatch and Transaction can be configured to perform granular merges instead of overwriting the target documents in their entirety.
