LSM 写入流程及读取流程 上面提到了 LSM 的核心其实就是通过顺序写来解决大量写时的性能问题,又因为分层设计牺牲了部分读取性能,那么接下来就从“增删改查”的角度去理解它的读写流程及原理 从“增删改”来看写入流程 要预先说明的是,LSM 对所有数据的插入、修改、删除操作都是先写入 log,再保存到内存中,待数据...
由于LSM Tree必须保持仅追加样式更新的不变性以保持写性能,因此在LSM Tree中删除内容与向日志中追加键值条目相同,而是将一个称为“墓碑”的特殊字节序列写入值。它可以是任何字节序列,应该是唯一的,以区别于其他可能的值。现有的旧值稍后在压缩阶段被删除。 读取LSM树中的数据 LSM树中的所有读取都首先从Memtable中...
LSM = 1 30 passes Render time: 05:05 The same number of samples (16) is used for both GI and direct light. Note that the quality of GI the GI pass remains the same as when using the default settings, but the quality of the direct lighting pass is lower. Render time is also sligh...
