RYA as triple stores questions?

["Ly, Kiet" <Ki...@finra.org>]

We are trying to evaluate RYA as potential semantic data lake running on EMR cluster. If I can get some answer to these questions, it would help us greatly.

What is the largest triples store currently in production using RYA in term of billion/trillion of triples?
Any of the production installation running on EMR in AWS? If yes, what is the instance types, #of nodes, # of zookeepers, etc..
Are there any hard limitations (# of nodes, min/max memory, etc…)?
Any operational issues with Accumulo? We had a lot of experience with Hbase but not with Accumulo.

I know. It is the best way the reach at a lot of people at once. 
Of course, if any want to share the deployment info please email me privately kiet.ly@finra.org.


I saw your list of inference properties (rdfs/owl) and it is very basic. Is there plan to improve it?
Bring in OWL 2 reasoner (Pellet/Hermit)?. I will attend the bimonthly meeting later today.

Hi Kiet,
I'm not sure that a lot of us can disclose over the dev list a lot of the
places that Rya is currently running operationally.
As far as your other questions, I'm not aware of any hard limitations
though I'm not sure I understood the question -- maybe Aaron or Adina (or
someone else) might have more insight?
I haven't heard of many operational issues with Accumulo, other than a lot
of performance can be configuration dependent.  Accumulo has a lot of
documentation on configuration and installation.  If you have more
specifics about your particular deployment, we may be able to help more.
