Database scalability

Database Scalability Nuno Peralta & João Proença I. INTRODUCTION Every day, Internet is growing and everyone is switching over to online services. Therefore, there must be methods to support the large traffic that big websites, such as Google, Facebook and Microsoft, get every second. As the users keep growing, and database as well, the server will start having issues with its resources. MySQL server, connections, system backups, CGI scripts… everything is using Memory and CPU. Downtimes will begin and headaches too. We’ll be talking about some database scalability methods that the biggest websites use today. While new approaches are being implemented by them, at the same time they are collaborating with the services that small companies’ servers use. Facebook helps on the development of MySQL, PHP and Memcached [1]. [1] Facebook (Jan 2012). Open Source - Facebook Developers. https://developers.facebook.com/opensource/ II. NON-RELATIONAL DATABASES MySQL is a relational database and is designed to be used as a relational database. So, because of that, it is relatively slower than a non-relational database. MongoDB is a non-relational and NoSQL database, it is a document-oriented storage [2]. This doesn’t mean that one is better than the other, because MySQL and MongoDB are designed to different purposes, and will perform better on what they were designed to. MongoDB’s “inserts” are much faster than MySQL’s, because MongoDB inserts all data in the RAM and…

técnicas de escalabilidade, classificação e arquitetura do NoSQL, que é um banco de dados não relacional que tem um propósito de suprir as necessidades em demandas onde os bancos de dados tradicionais (relacionais) são ineficazes. O NoSQL é bastante utilizado pelas grandes empresas, como o Twitter, Facebook, Ebay, Google, entre outros. A sua principal característica é a escalabilidade, no qual faz aumentar a capacidade de armazenamento de dados e a velocidade. Palavras-chave:…

(services) could be run in the grid – These should be as big as possible (see later scalability issues) – Here end-users would not need grid certificate and their life would be much easier Service grids would work as SaaS clouds • Users can call predefined services • The services are executed either in a service grid or in a cloud • The user must not notice the difference in the case when the cloud is an academic one • Advantage – Service grids have the same simple user…

delivers connectivity and integration for transactional systems, so we see no need for a CDBMS to cater for transactional traffic - only query traffic. A CDBMS needs to scale across large computer grids, but it also needs to be able to span multiple data centers and, as far as is possible, cater for slow network connections. We review traditional databases, focusing primarily on relational databases and column store databases, concluding that such databases, as currently engineered, could…
