MySQL Multi Source Replication
+1 Vote Up -0Vote Down

Send to Kindle

Na semana passada, durante o evento MySQL Connect, foi lançada a versão de testes do MySQL 5.7 (MySQL 5.7.2 DRM), dentre as novas funcionalidades, uma que chamou bastante a minha atenção foi a replicação de múltiplos masters (multi source replication). Atualmente o MySQL não possui uma funcionalidade oficialmente (build-in) , pode se conseguir esse resultado com alguns hacks, como, a cada x segundos executar um change master to no slave para ficar trocando de master, mas como o nome diz, isso é um “hack”.

I need more space on my f/s to get installing. I was a bit of a scrooge when I created my Oracle Linux virtual machine, so now I’m paying the price.
