Joel Bernstein updated SOLR-7535:
---------------------------------
Attachment: SOLR-7535.patch
New patch that wraps the stream source in a PushbackStream. This allows us to
push back the EOF tuple and upload the batch. This is a nice approach that
preserves the EOF tuple from the source stream in case there is info in the EOF
tuple.
Existing tests are passing with this patch.
I'll spend some time today expanding the tests.

> The ticket adds an UpdateStream implementation to the Streaming API and
> streaming expressions. The UpdateStream will wrap a TupleStream and send the
> Tuples it reads to a SolrCloud collection to be indexed.
> This will allow users to pull data from different Solr Cloud collections,
> merge and transform the streams and send the transformed data to another Solr
> Cloud collection.
