WebImplement and demonstrate a disk-based buffer pool class based on the LRU bufferpool replacement strategy. Disk blocks are numbered consecutively from the beginning of the file with the first block numbered as 0. Assume that blocks are 4096 bytes in size. WebThe algorithm used to determine what to throw out is the cache's replacement strategy or policy. ... Once the node is stored in the buffer, no buffer replacement is required. When the number of nodes in the tree exceeds the buffer size, the buffer cannot accommodate all necessary tree nodes simultaneously. Thus, the buffer-miss rate increases ...
