WebThe btree module implements a simple key-value database using external storage (disk files, or in general case, a random-access stream ). Keys are stored sorted in the database, and besides efficient retrieval by a key value, a database also supports efficient ordered range scans (retrieval of values with the keys in a given range).

Any data type that can be sorted into a well-defined linear order can be indexed by a btree index. The only limitation is that an index entry cannot exceed approximately one-third of a page (after TOAST compression, if applicable).

WebB-trees are always completely balanced, with each leaf the same distance from the root. The mechanism for balancing a B-tree is that when a node becomes full, it splits into two nodes and pushes a key up into its parent. For example, we might split a three-key node into two one-key nodes like this: 14 38 57 A B C D (38) 14 57 A B C D WebNov 6, 2007 · If you have suggestions, corrections, or comments, please get in touch with Paul Black..
