------------------------------------

             Summary: Oak-run indexing can miss entries with mongoParallelDump enabled
                 Key: OAK-12466
                 URL: https://issues.apache.org/jira/browse/OAK-12466
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: indexing
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller


Parallel downloading stops when the ascending and descending streams cross, but one stream may still hold downloaded documents in an unflushed buffer. 

Indexing can proceed without waiting for that buffer to be delivered, which can result in incomplete indexes. 

Very narrow includedPaths (restrictive MongoDB path) filtering makes this scenario more likely, because it can have long gaps between returned batches.
