Joel Bernstein commented on SOLR-7535:
--------------------------------------
The UpdateStream worked well during manual testing. The test involved streaming
5 million documents from a source collection into a separate destination
collection. I used very small documents for the test which loaded at a rate of
about 20,000 documents per second. The stream from the source collection was
moving at a rate of over 1 million documents per second so there was
significant blocking on the export. This did not cause any problems. I tested
loading from a single node and in parallel with two nodes. No performance
increase could be seen in parallel mode because I believe my laptop was already
maxed out. In theory when indexing to a large cluster we would see performance
improvements when indexing in parallel.
I believe this ticket is now ready to commit.
I ran into a few "ease of use" issues that made it tricky to get the update
expression running. I fixed a couple of these issues as part this ticket and
I'll open another ticket to address the others.

> 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.
