Can a virtuoso cluster be treated as a virtual single instance? To
expand:
Say I have a cluster of 4 virtuoso instances with one of them
configured as a master. Now, I have to load the cluster with say 3
billion triples belonging to say 5 different graphs.
1. I just load the data into the master server and virtuoso clustering
takes care of spreading the data into the different servers as it sees
fit? Also, is the data partitioned into the different servers or is it
just replicated?
You can load across all 4 instances in parallel. That's the very essence
of the horizontal partitioning that underlies our cluster engine. It's
one virtual database in a sense where access to any node delivers access
to the entire parallelized cluster.
2. When I have to query this data say from 3 interconnected graphs,
then I just run the query against the master cluster and virtuoso
cluster will take care of fetching the partitioned data(assuming it is
partitioned) from the different instances?
Are my assumptions correct?
You talk to Virtuoso as you would the single server edition from any
port. The cluster engine deals with the rest of the work :-)
