架构图03：NDB Cluster

This chapter provides information about MySQL NDB Cluster, a high-availability, high-redundancy version of MySQL adapted for

the distributed computing environment, as well as information specific to NDB Cluster 8.4 (NDB 8.4.0),

based on version 8.4 of the NDB storage engine.

MySQL NDB Cluster uses the MySQL server with the NDB storage engine.

Support for the NDB storage engine is not included in standard MySQL Server 8.4 binaries built by Oracle.（注意，该方式搭建的集群需要付费的。）

MySQL NDB Cluster does not support InnoDB Cluster, which must be deployed using MySQL Server InnoDB storage engine

as well as additional applications that are not included in the NDB Cluster distribution.

MySQL Server 8.4 binaries cannot be used with MySQL NDB Cluster.

25.2 NDB Cluster Overview

https://dev.mysql.com/doc/refman/8.4/en/mysql-cluster-overview.html

NDB Cluster is a technology that enables clustering of in-memory databases in a shared-nothing system.

The shared-nothing architecture enables the system to work with very inexpensive hardware, and with a minimum of specific requirements for hardware or software.

Chapter 23 InnoDB Cluster

https://dev.mysql.com/doc/refman/8.4/en/mysql-innodb-cluster-introduction.html

This chapter introduces MySQL InnoDB Cluster, which combines MySQL technologies to enable you to deploy and administer a complete integrated high availability solution for MySQL.

An InnoDB Cluster consists of at least three MySQL Server instances, and it provides high-availability and scaling features. InnoDB Cluster uses the following MySQL technologies:

》MySQL Shell,

which is an advanced client and code editor for MySQL.

》MySQL Server, and Group Replication,

which enables a set of MySQL instances to provide high-availability. InnoDB Cluster provides an alternative, easy to use programmatic way to work with Group Replication.

》MySQL Router,

a lightweight middleware that provides transparent routing between your application and InnoDB Cluster.
