O Bigtable é um sistema de armazenamento de dados proprietário compactado, de alto desempenho construído no sistema do Google File e algumas outras tecnologias Google. Em 6 de maio de 2015, uma versão pública do Bigtable foi disponibilizada.[1][2]
O desenvolvimento do Bigtable começou em 2004[3] e agora é usado por várias aplicações do Google, como o indexamento web,[4] MapReduce, que é usado frequentemente para gerar modificar dados armazenados no Bigtable,[5] Google Maps,[6] Google Book Search, Google Earth, Blogger.com, Google Code, YouTube,[7] e Gmail.[8] As razões do Google para desenvolver seu próprio banco de dados incluem escalabilidade e melhor controle das características de desempenho.[9]

First an overview. Bigtable has been in development since early 2004 and has been in active use for about eight months (about February 2005).

There are currently around 100 cells for services such as Print, Search History, Maps, and Orkut

Their new solution for thumbnails is to use Google’s Bigtable, which provides high performance for a large number of rows, fault tolerance, caching, etc. This is a nice (and rare?) example of actual synergy in an acquisition.

- ↑ Chang et al. 2006, Conclusion: ‘We have described Bigtable, a distributed system for storing structured data at Google... Our users like the performance and high availability provided by the Bigtable implementation, and that they can scale the capacity of their clusters by simply adding more machines to the system as their resource demands change over time... Finally, we have found that there are significant advantages to building our own storage solution at Google. We have gotten a substantial amount of flexibility from designing our own data model for Bigtable.’
