microservice structure

Some time ago I read some TCP/IP protocol stack things. There are many things I want to write and I don't have time to do. //************************************** ************************************ /* 1. Each opened file, socket, and so on are represented by a file data structure. In this way, the file and socket are differentiated by members in inode-> U (union:Struct inode {.....................Union {Struct ext2_inode_info ext2_ I;Struct ext3_i

Redis data structure (2) dictionary, redis Data Structure dictionary The Redis dictionary is actually a Hash table. Its implementation is similar to the hashmap structure in JAVA. Key-Value pairs are stored in Key-Value mode, but there are some differences.The hashmap structure in java contains the hash table and impl

C/S structure software (Client/Server mode)It is divided into two layers: client and server. The client is not an input/output device with no computing capability, but has certain data processing and data storage capabilities, by reasonably assigning the computing and data of application software to the client and server, the network traffic and server computing workload can be effectively reduced. Due to restrictions on the number of server connectio

Data is a general term describing the numbers, characters, and all kinds of symbolic sets that can be entered into a computer and accepted by a computer. Basic unit: Data element Identifying Data elements: Keywords (keyword) Unique keywords for identifying data elements: PRIMARY key (primary keyword) Minimum identity unit in Data element: Data item Data structure (structure): a relationship between elements

C + + structure arrayA structural body variable can hold a set of data (such as a student's number, name, grade, etc.). If there are 10 students whose data needs to be in operation, it is obvious that an array should be used, which is the structure array. The difference between an array of structures and a numeric array that was previously introduced is that each array element is data of a struct type, each

I believe you often see comparison of some PHP applications, said with Isset () to replace strlen (), isset faster than strlen execution speed. Example: if (Isset ($user)) { Do some thing } The reason is that isset is a language structure, and strlen is a function. And Echo is a language structure, not a function. What is the language structure? Is it different f

Chapter 4 cycle structure, Chapter 4 Cycle Structure 1. Features of the loop structure: 1) not endless 2) It will continue only when certain conditions are met. It is called a "cyclic condition" 3) Exit the loop structure when the condition is not met 4) The loop structure i

Harvard Structure The Harvard structure isSeparate storage structure of program instruction storage and data storage. The central processor first reads the content of the program instruction in the program instruction memory, decodes the content, obtains the data address, reads the data in the corresponding data storage, and performs the next operation (usually e

Data structure (C implementation) ------- string, data structure ------- A string (string for short) can be considered as a special linear table. Its particularity lies in that the data element type of a linear table is always character, and the data objects of a string are constrained to character sets. A string is a finite sequence consisting of 0 or more characters. It is generally recorded as: s = "s1 s

Tigase database structure (1), tigase database structure There are many tables in the Tigase database. The most important tables are three: tig_users, tig_nodes, and tig_pairs. 1. tig_users Tig_users stores user information, including uid (primary key, user ID), user_id (user name), usr_pw (User Password), and other fields. 2. tig_nodes Tig_nodes is used to store node information (used to express data in l

Data structure, data structure, and algorithm. Data structure, data structure, and algorithm linear table: a finite sequence of zero or more data elements (note: The following are all integer data simulations) A sequential storage structure (using a segment of address to con

Concept Structure Design and Billing System Structure Design The general process of database design must be known to everyone. People who do not know can easily find relevant information on the Internet. Generally, we divide database design into six stages, that is, the requirement analysis stage, conceptual structure design stage, logical

Why is B + tree used? Simply put, it is because the files are large and cannot be fully stored in the memory. Therefore, it is necessary to store the files to the disk. Application of B + tree in database { Why is B + tree used? The reason is: 1. files are large and cannot be stored in the memory. Therefore, they must be stored on disks. 2. the structure of the index should minimize the number of disk I/O accesses during the search process (why to us

I. MBR partition structure MBR disk partitioning is the most widely used partition structure. It is also called DOS partition structure, but it is not only used on Windows systems, but also in Linux, x86-based UNIX and other system platforms. It is located in the first sector of the disk 0, one sector is equal to 512 bytes), is an important sector referred to as
