BlueStore的诞生就是替代FileStore存储引擎,最早再Jewel版本引入,用于在SSD上替代传统的FileStore,作为新一代的高性能存储引擎,BlueStore在设计中充分考虑了对SSD以及NVME的适配,针对FileStore的缺陷,BlueStore选择绕过文件系统,自己直接管理裸设备,自己直接对数据进行IO操作,同时把元数据放在RocksDB中,大大缩短了整个对象存储...
缓存、内存、CXL Memory、SCM存储类内存、NVMe SSD和HDD在多个方面存在显著的区别,包括它们的功能、结构、性能以及网络延迟等。 Cache:缓存是位于CPU和主内存之间的小容量存储器,用于存储CPU经常访问的数据和指…
Twitter从Ruby转向JAVA的实践证明:Cache 缓存 + JVM微调是Java/JVM的核心竞争力,这也是最容易被我们忽视的,因为很多使用Java系统(包括Spring + Hibernate)只是当作SQL语句的包装器来使用,负载主要集中在数据库上,根本不会使用In-memory Cache。 对象缓存恰好是领域模型和Java内存模型之间的衔接物,通过引入缓存,将领域模...
On the other hand, secondary memory is often housed in a separate storage device such as a hard disc drive or solid-state drive (SSD), which is linked to the computer system either directly or over a network. Secondary memory has a far cheaper cost per gigabyte, but the read and write...
A method for predicting SSD memory cache occupancy can include processing write requests, predicting content occupancy of an SSD's cache, determining whether an address in the cache is probably logically contiguous to the logical memory address, re-directing at least one write request, and ...
This post delves into caching concepts, use cases, and popular tools to empower data architects and engineers in building high-performance data solutions. 2. Caching: What, Why, and Where Caching is a technique used to manage frequently accessed data in-memory. The method facilitates access to ...

have the same size, which is one-third of the cache size. This means that there are only three places in the cache to which any object can map, since the sum of the objects' sizes equals the memory size, and the cache is direct-mapped. The problem instance is illustrated inFigure ...
