Multi-Data Center Scalability

Geographic Replication

• Replicate complete

clusters across data

centers

– DR & data locality

– Fully active/active

– No passive resources

• Split individual clusters

across data centers

– Synchronous replication

& auto-failover between

sites

– Delivered as part of

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;

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;
