Drawing a picture is actually easy to see.Co

Feel some difficult problem, just started to think of the establishment of virtual node, but the implementation is always wrong, because each time the virtual node is established, the original node and virtual node can not be separated, resulting in virtual node is meaningle
. If there is inconsistent data, record the data first, and record which nodes have that data, and which nodes do not exist for that record. The node cursor that records the minimum OID is then moved down, and cursors of multiple nodes may be moved. Because the OID is the smallest node, moving down one is the next record that is most likely to match. Follow this method to move the cursor gradually to the en
