B-Tree Index B-tree index is the widely used data structures for tree based indexing in DBMS. It is a multilevel format of tree based indexing in DBMS technique which has balanced binary search trees. All leaf nodes of the B tree signify actual data pointers. Moreover, all leaf nodes ar...
如果我们在 id 字段上创建了索引(例如 B-树索引),数据库查找的过程大概如下图所示: B-树(平衡树、Balanced Tree)索引就像是一棵倒立的树,其中的节点按照顺序进行组织;节点左侧的数据都小于该节点的值,节点右侧的数据都大于节点的值。 数据库查找时,首先通过索引找到工号为 5 的节点,再通过该节点上的指针(通常...

假设这次写入导致 root, branch 都发生了变化,这种 in-place 的更新反映到磁盘上就是: 基本是2次读 IO和写2次写 IO+WAL fsync,粗略为4次随机 IO。通过分析发现,B-tree 对写操作不太友好,随机 IO 次数较多,而且 in-place 更新必须增加一个 page 级的 WAL 保证失败回滚,简直是要命。
