## Caveats | ||||||||||||||
|
||||||||||||||
### Automatic swapping for horizontal sharding | ||||||||||||||
### Troca automática para fragmentação horizontal | ||||||||||||||
|
||||||||||||||
While Rails now supports an API for connecting to and swapping connections of shards, it does | ||||||||||||||
not yet support an automatic swapping strategy. Any shard swapping will need to be done manually | ||||||||||||||
in your app via a middleware or `around_action`. | ||||||||||||||
Embora o Rails agora suporte uma API para conectar e trocar conexões de _shards_, ele faz | ||||||||||||||
ainda não suporta uma estratégia de troca automática. Qualquer troca de fragmentos precisará ser feita manualmente em sua aplicação por meio de um _middleware_ ou `around_action`. | ||||||||||||||
|
||||||||||||||
### Load Balancing Replicas | ||||||||||||||
### Réplicas de balanceamento de carga | ||||||||||||||
|
||||||||||||||
Rails also doesn't support automatic load balancing of replicas. This is very | ||||||||||||||
dependent on your infrastructure. We may implement basic, primitive load balancing | ||||||||||||||
in the future, but for an application at scale this should be something your application | ||||||||||||||
handles outside of Rails. | ||||||||||||||
O Rails também não suporta balanceamento de carga automático de réplicas. Isto é muito | ||||||||||||||
dependente de sua infraestrutura. Podemos implementar balanceamento de carga básico e primitivo | ||||||||||||||
no futuro, mas para uma aplicação em escala, isso deve ser algo que sua aplicação | ||||||||||||||
lida fora do Rails. | ||||||||||||||
|
||||||||||||||
### Joining Across Databases | ||||||||||||||
### Join entre Bancos de Dados | ||||||||||||||
|
||||||||||||||
Applications cannot join across databases. At the moment applications will need to | ||||||||||||||
manually write two selects and split the joins themselves. In a future version Rails | ||||||||||||||
will split the joins for you. | ||||||||||||||
As aplicações não podem fazer `join` entre bancos de dados. No momento, as aplicações precisarão | ||||||||||||||
escrever manualmente dois *selects* e dividir as próprias *joins*. Em uma versão futura do Rails | ||||||||||||||

### Schema Cache | ||||||||||||||
### Cache de Esquema | ||||||||||||||
|
||||||||||||||
If you use a schema cache and multiple databases you'll need to write an initializer | ||||||||||||||
that loads the schema cache from your app. This wasn't an issue we could resolve in | ||||||||||||||
time for Rails 6.0 but hope to have it in a future version soon. | ||||||||||||||
Se você usar um *cache* de esquema (*scheme*) e vários bancos de dados, você precisará escrever um inicializador | ||||||||||||||
que carrega o *cache* de esquema da sua aplicação. Não era um problema que pudéssemos resolver em | ||||||||||||||
tempo para Rails 6.0, mas espero tê-lo em uma versão futura em breve. | ||||||||||||||
