The document provides an overview of MySQL Cluster, a database clustering product. It describes the key components of MySQL Cluster - management nodes, data nodes, and SQL nodes. It explains how MySQL Cluster provides high availability and automatic partitioning of data across nodes. Benchmarks show that MySQL Cluster can scale out to improve performance and handle increased load by adding more nodes.

9. MySQL Cluster
• O MySQL Cluster é formado por 3 componentes:
– Management Node: permite a realização de tarefas
administrativas como monitoramento dos nós, backup dos
nós de dados do cluster e outras – seu binário é o ndb_mgmd;
– Data ou Storage Node: responsável por processar e
armazenar dados dos bancos de dados localizados no cluster
– seu binário é o ndbd ou ndbmtd;
– API ou SQL Node: este é o nó que recebe as conexões das
aplicações e enviam e requisitam dados armazenados nos
Data Nodes – seu binário é o mysqld;

25. MySQL Cluster
• Recomenda-se que:
– todos os componentes sejam pelo menos duplicados, tendo
uma instalação com no mínimo 6 nodes dentro do cluster;
– o cluster seja colocado em uma sub-rede que possibilite
trafegar dados somente do cluster para que não haja perda
de pacotes;
– todas as máquinas que figuram SQL e Storage node tenham
as mesmas configurações para evitar bottlenecks;
– todos os binários de todos os componentes sejam da mesma
versão e release do produto;
