tree索引結構的locality存取模式來聚集blob的更新部份,達到減少快閃記憶體的page-read,page-write及erasure次數的目的.Blob包含的node為B-tree之subtree,也就是B-tree索引結構會由數個blob所構成.實作blob方法包含blob的split/merge及修正後的garbage collection.效能評估方面以B-tree on NFTL與blob的實作方式比較,有...
从B树到B+、B*再到B-linked-tree的一些学习总结。 1 B树用阶(order)定义 Every node has at mostmchildren. Every non-leaf node (except root) has at least ⌈m/2⌉ child nodes. The root has at least two children if it is not a leaf node. ...
