B tree vs. B+ tree

Pros of B tree

  • Data associated with each key ⟶ frequently accessed nodes can lie closer to the root, and therefore can be accessed more quickly.

Pros of B+ tree

  • No data associated in the interior nodes ⟶ more keys in memory ⟶ fewer cache misses
  • Leaf nodes of B+ trees are linked ⟶ easier to traverse ⟶ fewer cache misses
