* Será necessário atualizar a lógica das aplicações para trabalhar com os fragmentos, o que pode resultar em consultas SQL complexas.
* Distribuição dos dados pode se tornar desigual num fragmento. Por exemplo, um conjunto de usuários bastante ativos num fragmento pode resultar em aumento de carga para s fragmento, comparado aos outros.
* Rebalanceamento aumenta complexidade. Uma função fragmentada baseada em [hashing consistente](http://www.paperplanes.de/2011/12/9/the-magic-of-consistent-hashing.html) pode reduzir a quantidade de dados transferidos.
* Relacionar dados de múltiplos fragmentos é mais complexo.

#### Denormalization
#### Desnormalização

Denormalization attempts to improve read performance at the expense of some write performance. Redundant copies of the data are written in multiple tables to avoid expensive joins. Some RDBMS such as [PostgreSQL](https://en.wikipedia.org/wiki/PostgreSQL) and Oracle support [materialized views](https://en.wikipedia.org/wiki/Materialized_view) which handle the work of storing redundant information and keeping redundant copies consistent.

#### SQL tuning
#### Ajuste de SQL

SQL tuning is a broad topic and many [books](https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=sql+tuning) have been written as reference.
