The distributed command mode is a recommended mode for architecture design. Compared with the design of common applications, it should be considered more in the interconnected system. The goal of this model is to have the same design for both an independent system and an interconnected system. This mode allows developers to focus on designing a common application that follows the command mode without considering that the application will be connected to other

Linux has the most notable features of flexibility and scalability, such as its Virtual File System switch (VFS ). You can create a file system on a variety of devices, including traditional disks, USBFlash drive, memory, and other storage devices. You can also embed a file system in another file system environment. Explore the factors that make VFS so powerful and understand the main interfaces and processes of VFS.

In the first part of "Designing Data-intensive Applications" (see above), the basic theory and knowledge of the data system are introduced, all based on single node. In the second part of the Ddia (distributed data), the field of view is extended to the distributed Data system. There are three main reasons for the distribution of data:
Scalability
Fault Tolerance/high Availability
Reduce Latency
When the load increases, there are two ways to respond, scale up vs. scale out, whi

The purpose of this book
Operating System is an old topic. Its appearance and development are of great significance to computer technology. This development is not only reflected in traditional computers, but also plays an irreplaceable role in the embedded field that emphasizes streamlining, high efficiency, and real-time performance.

Frankly, it is also a chance coincidence, in the postgraduate stage into the field of distributed systems learning. Whether it's large-scale storage or computing, its core is the need to use distributed technologies to leverage parallelism to address data-intensive applications.

The file system is the short name of a file management system, which, according to Wikipedia, is used to organize how data is stored on storage media and how it is retrieved. Without a file system, the information on the storage medium will be a large piece of information, there is no way to know when a message will end, and can not know when the information began, the management of information will be very troublesome.?? There are many types of file systems

As a saying, I would like to give some suggestions to students eager to learn embedded systems:
(1) the software and hardware of embedded systems are closely related, so we must lay a solid foundation for software and hardware. In fact, as long as you find the correct method and work hard, any science and engineering students, or even non-science and engineering students, can learn embedded
A file system is a directory structure that includes storage devices or partitions. Generally, an application storage device can contain one or more file systems. Generally speaking, a file system stores files or data in an organized manner, with the aim of making it easy for the operating system to query and access data. Common file systems include FAT3, NTFS, Ext3, and Reiserfs. However, different operati

1. Background
Many companies' platforms generate a large number of logs (generally stream data, such as search engine PVs and queries) every day. to process these logs, a specific log system is required. Generally, these systems must have the following features:
(1) build bridges between application systems and analysis
the metadata information.
Obviously, the larger the file system to be detected, the longer the detection process takes. For partitions with a size of dozens of G, it can take a long time to detect. As Linux starts to be used for more and more important applications in large servers, it is becoming more and more intolerable for long time machines. This requires more sophisticated and sophisticated file systems to replace Ext2.
Therefore, the log-file
