IndexScan doesn't dedup if index becomes multikey during query execution

XMLWordPrintableJSON

    • ALL

      IndexScan currently sets _shouldDedup based on the value of isMultiKey at the start of the query. This is incorrect since the index may later become multikey. Note that it isn't enough to recheck isMultiKey after yielding since we would need to know all RecordIds we've already returned.
