I am dealing with a huge dataset consisting of key-value pairs. The queries are always in the form of range queries on the key space (keys are numbers) hence any persistent B-Tree like structure will
I need to do a preorder traversal of a Btree, and among other things, print the following information for each page (which is the same thing as a node):
I\'m going to be writing a general object class for use with zodb.These objects will add themselves to a btree index once they are persisted to the zodb object graph.
If we are looking for line intersections (horizontal and vertical lines only) and we have n lines with half of them vertical and no intersections then
If I insert the letters A, G, I, and Y into a B-tree of order 4 (meaning 4 pointers and 3 elements in each node), I get the following B-tree.
In this B+ tree 5 开发者_运维百科appears twice. B+ treeFrom Wikipedia: In a B+ tree, in contrast to a B-tree, all records are stored at the leaflevel of the tree; only keys are stored in interior n
When a node in a B-tree is split, are keys from the original node duplicated in the new nodes?What\'s the purpose of 开发者_开发技巧doing this?Isn\'t this inefficient?No. It\'s all done with pointers.
Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.
I have a text file which contains some info on extents about all the files in the file system, like below
How do you figure out the maximum depth of a B-tree? Say you had a B-tree of order 1625, meaning each node has 1625 pointers and 1624 elements.
