这个连接RocksDB和Zoned Storage的插件就是ZenFS,它做的事情大概就是将大文件分配在不同的Zone之中。此外ZenFS还会执行Write lifetime hints (WLTH) 评估数据的生存时间,把生存时间相近的数据丢进同一个Zone里。需要注意的是,ZenFS中WLTH和垃圾回收(准确的说应该是压缩LSM-tree)的功能是RocksDB提供的,所以它并...
ZenFS需要根据文件的offset来查找对应的extent(代码参考ZoneFile#GetExtent),在由extent去定位目标Zone,而BlueFS其实是把每个Zone当成了extent来管理,并且extent大小固定,这样便可以通过offset直接计算出目标数据在哪个Zone上,而不需要遍历一次extent链表。 (2) 不在需要考虑数据迁移问题 由于每个Zone只被一个SSTable占有,...
ZenFS: RocksDB Storage Backend for ZNS SSDs and SMR HDDs ZenFS is a file system plugin that utilizes RocksDB's FileSystem interface to place files into zones on a raw zoned block device. By separating files into zones and utilizing write life time hints to co-locate data of similar lif...

在AI与数据管理上,ZNS技术也展现了广阔的应用前景。结合如RocksDB这样的新型数据库,开发者可以利用ZNS的开放性,打造高效的数据处理系统。ZenFS、RocksDB与ZNS SSD的结合能够极大增强存储性能,并在数据处理速度和效率上取得质的飞跃。 回顾ZNS的演化历程,我们看到机会与挑战并存。虽然ZNS在减少OP(Over-Provisioning)空间...
