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.

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.'
