eBay actually has an open source distributed triple store they released recently: https://github.com/eBay/akutan
Seems to me they'd be using it internally.

What Hacker News says
9 sourcesCould you compare this to eBay's distributed triple store https://github.com/eBay/akutan ?
Looks like it is written in Go too. I can see your's being much simpler to get up and running initially though. Looks like akutan isn't as simple since its built on docker and is a daemon.
In Fabric – A simple triplestore written in GoMay be useful:

In Ask HN: I'm trying to represent an entire building as a graphArchitectural decisions explained here: https://github.com/eBay/beam/blob/master/docs/central_log_ar...
The architecture is: materialized views from a central append log.
I don't see a reference to Apache Bookkeeper[1][2] in the above. My recommendation to anyone who wants to build their own variant of this architecture is to build it on top of Bookkeeper instead of rolling your own. It is designed for this precise workload [2] and addresses the write throughput limitations of the OP 'Beam'.
[edit: pull quote from [2]]:
"what makes BookKeeper unique is its ability to offer a short-tailed, low-latency, distributed scale-out storage solution. Although this is a CP system, its greater availability makes it almost a C(A)P system. It is an apt storage for immutable data."
