Description
When pulling unordered data from an index with multiple shards, data gets lost if the fetchSize is not a multiple of the shard count, as the persisted cursor position to continue paging is based on the last seen
_docwhich is duplicated when the primary shard count exceeds 1. This PR currently adds a reproducer for the bug -- finding a fix is still in progress.Related Issues
