Description

Streaming expressions currently supports an update(...) decorator function for wrapping another stream and treating each Tuple from the inner stream as a document to be added to an index.

I've implemented an analogous subclass of the UpdateStream called DeleteStream that uses the tuples from the inner stream to identify the uniqueKeys of documents that should be deleted.
