------------------------------------
Summary: Ensure that all Documents are read with document order
traversal indexing
Key: OAK-7074
URL: https://issues.apache.org/jira/browse/OAK-7074
Project: Jackrabbit Oak
Issue Type: Improvement
Components: mongomk, run
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.8
With OAK-6353 support was added for document order traversal indexing. In this
mode we open a DB cursor and try to read all documents from it using document
order traversal. Such a cursor may remain open for long time (2-4 hrs) and its
possible that document may get reordered by the Mongo storage engine. This
would result in 2 aspects to be thought about
# Duplicate documents - Same document may appear more than once in result set
# Possibly missed document - It may be a possibility that a document got moved
and missed becoming part of cursor.
Both these aspects would need to be handled
