commit ccac76734312430083cd6a4bff4219ff67d65f57
Author: Nick Vatamaniuc <va...@apache.org>
AuthorDate: Sat Feb 15 12:27:25 2020 -0500

    Use {restart_tx, false} option in view index builder changes feed
    
    Index builder performs writes in the same transaction as the changes
    feed so we can't use iterators as they disable writes.
