Olá, UK's Government Communications Headquarters (GCHQ) open-sources surveillance graph database software on GitHub.
"Gaffer is distinguished from other graph storage systems by its ability to update properties within the store itself. For example, if the edges in a graph have a count statistic, then when there is a new observation of an edge, the edge can simply be inserted into the graph with a count of 1. If this edge already exists in the graph then this count of 1 will be added onto the existing edge. The ability to do these updates without the need for query-update-put is key to the ability to ingest large volumes of data. Many types of statistics are available, including maps, sets, histograms, hyperloglog sketches and bitmaps used to store timestamps." The general consensus on Hacker News is that Gaffer is actually rather neat, if you're looking for a mega-scale graph database. http://arstechnica.co.uk/business/2015/12/gchq-open-sources-surveillance-graph-database-software-on-github/ Baseado no https://en.wikipedia.org/wiki/Apache_Accumulo Boa sorte. -- André Felipe Machado CEAGO/COTSC/COSTE As Lou Gerstner, former Chairman and CEO of IBM, observed: 'I came to see, in my time at IBM that culture isn’t just one aspect of the game; it *IS* the game.' ------------- - "Esta mensagem do SERVIÇO FEDERAL DE PROCESSAMENTO DE DADOS (SERPRO), empresa pública federal regida pelo disposto na Lei Federal nº 5.615, é enviada exclusivamente a seu destinatário e pode conter informações confidenciais, protegidas por sigilo profissional.
