Maintain “links” when writing a B+ tree to disk?
问题 I have done the implementation of B+ tree in java , but as usual , that is completely in main memory. How can i store a B+ tree onto a disk ? Each node of the btree contains the pointers(main memory addresses or reference to objects) to its children , how can i achieve the similar thing while Btree resides on disk? What replaces main memory addresses in b+ tree nodes in the scenario when b+ tree is on disk ? There is already a similar Question posted here : B+Tree on-disk implementation in
