With the continuous expansion of business scale, rapid growth of data, and increasingly higher requirements for data systems, the database system has become a crucial component, and YugaByte DB (hereinafter referred to as YugaByte) is an open source distributed database. It provides a solution that goes beyond traditional databases to support a scalable, elastic, and secure cloud-native data platform. This article will explain the design concept, data model and storage structure of YugaByte DB, and demonstrate the capabilities that YugaByte DB can provide in enterprises through practical cases.
2. Explanation of basic concepts and terms
Distributed database
What is a distributed database?
Distributed Database refers to a database system that decomposes a complete database system into multiple independent subsystems and enables communication and coordination between them. The purpose of a distributed database is to improve the fault tolerance and availability of the database system and allow each node in the system to be divided into different servers according to its own functions. The current mainstream distributed databases include MySQL Cluster, PostgreSQL Citus, MongoDB Sharding, etc.
Why use a distributed database?
First, distributed databases can provide higher performance, reliability, and fault tolerance. Secondly, it can solve the problem of single point of failure and scale the performance and processing load by adding more nodes. Third, a distributed database can improve database security because it can replicate data between different data centers and all data is transmitted encrypted. Finally, distributed databases enable cloud-native data platforms because they can be deployed in multiple types of environments, including private clouds, public clouds, hybrid clouds, and edge computing environments.
