... The structure of the leaf nodes of a B+ tree of order p is: • 1. Each leaf node is of the form <,,….,< ….,,Pnext>
where q<=p, each Pri is a data pointer and Pnext points to the next leaf node
of the B+ tree.
• 2. Within each leaf node, K1<= K2<=Kq‐1 for q<=p
• 3. Each ...

2 Buffer Trees
... Ignoring the recursive calls, emptying a buffer containing X items requires O(m + X/B) time. Under normal circumstances, we have X > M , so the total buffer-emptying time is O(X/B); if we amortize the cost of emptying a buffer against the X insertions that filled the buffer, the amortized time for a ...
