STX B+ Tree is a C++ template class software that facilitates the implementation of a B+ tree key/data container in computer memory.
This implementation of B+ tree follows the tree algorithms described in Cormen, Leiserson, and Rivest's Introduction into Algorithms, Jan Jannink's paper, and other algorithm resources. The classes come equipped with extensive assertion and verification mechanisms that help ensure the implementation's correctness by testing the tree invariants. Furthermore, the main B+ tree implementation can be located in the doxygen stx/btree.h, or with plain text comments btree.h.
The STX B+ Tree project is particularly noteworthy because it was developed with a strong focus on speed. The developers even performed a speed comparison test between the standard red-black tree and the new B+ tree implementation. The results of this test were quite impressive, showing the B+ tree implementation to be significantly faster. Overall, the STX B+ Tree project is an excellent choice for developers in need of a fast and reliable B+ tree key/data container in main memory.
