摘要

我们引入了许多日志，这是一个简单而新颖的日志概念，它在磁盘上部署了许多分散的日志，以便可以将小的随机写入添加到当前磁盘磁头位置(例如，最后一个大I/O的位置)附近的任何日志中。这样做的好处是双重的:小的写操作可以获得快速的持久性，而大的I/ o仍然可以维持大的带宽。

Manylogs: Improved CMR/SMR disk bandwidth and faster durability with scattered logs

We introduce manylogs, a simple and novel concept of logging that deploys many scattered logs on disk such that small random writes can be appended into any log near the current disk head position (e.g., the location of last large I/O). The benefit is two-fold: the small writes attain fast durability while the large I/Os still sustain large bandwidth.
