What are the implementation methods of distributed storage technology in PHP7.0?

With the development of Internet applications, the demand for data storage is increasing. Traditional data storage methods cannot meet the requirements of large capacity, high reliability, high performance, and high cost performance. Distributed storage technology can solve these problems. As a popular back-end language, PHP7.0 also supports distributed storage technology. This article will introduce the implementation methods of distributed storage technology in PHP7.0.

1. Distributed file system

Distributed file system is a technology that integrates the storage space of multiple servers into a large file system. It is fault-tolerant, scalable, efficient, and highly efficient. Available advantages. In PHP7.0, common distributed file systems include HDFS and GFS.

HDFS, the full name of Hadoop Distributed File System, is one of the core components of the Apache Hadoop framework. It is based on Google's GFS file system and MapReduce computing model and is used to store large data files and provide high reliability and high availability. In PHP7.0, you can use the HDFS API provided by Hadoop to interact with HDFS.

GFS, the full name of Google File System, is a distributed file system developed by Google and is mainly used to store Google’s big data. It has the advantages of high reliability, high availability, fault tolerance, scalability, etc. In PHP7.0, it can also interact with GFS through the corresponding API.

2. Distributed cache

Distributed cache is a technology that stores data dispersedly on multiple servers to improve the availability, performance and scalability of the system. In PHP7.0, commonly used distributed caches include Memcache and Redis.

Memcache is a high-performance distributed cache system that can store data on multiple servers to improve system performance and reliability. In PHP7.0, you can use the Memcache library to interact with Memcache.

Redis is a high-performance in-memory database that supports a variety of data structures and distributed operations. It can be used as a distributed cache, message queue, persistent storage and other purposes. In PHP7.0, you can use the phpredis extension or the Predis library to interact with Redis.

3. Distributed database

Distributed database is a technology that disperses and stores a large database on multiple servers to improve the performance, reliability and scalability of the system. In PHP7.0, commonly used distributed databases include MySQL Cluster and NoSQL databases.

MySQL Cluster is a cluster solution for MySQL database that supports parallel processing, load balancing, fault recovery and other features of multiple nodes. In PHP7.0, you can use the PHP API provided by MySQL Cluster for operations.

NoSQL database is a distributed storage database. Compared with traditional relational databases, it has higher scalability, high availability, performance and other advantages. In PHP7.0, common NoSQL databases include MongoDB, Couchbase and Cassandra, etc., which can be operated using the corresponding APIs.

Summary

With the rapid development of Internet applications, distributed storage technology has become the preferred solution for storing huge amounts of data. As a popular back-end language, PHP7.0 also supports a variety of distributed storage technologies. This article introduces the implementation methods of distributed file system, distributed cache and distributed database in PHP7.0, hoping to be helpful to PHP developers in distributed storage.
