Hello everyone,
I'm new in the world of graphs and orientdb. I have some questions and I'm
sure you can provide answers.
1 / some methods of connecting to the database exist in orientDB. I watched
the mode: plocal, memory and remote (requires running a server instance)
Orientgraph db = new OrientGraph (...)
a / are there others ways to connect to a database?
b / "remote" allows multiple connections to the base at the same time. Is
this the only way?
2 / To introduce you to the problem. We have an XML file as input about
200MB. The first step will be the creation of the graph database with
orientDb.
To give you an example, when creating a database from a document, we get:
680,000 vertices (fifteen classes, five to ten properties)
40,000,000 Edges (fifteen classes, five to ten properties)
We have to transform two hundred XML files that have the same type of data.
Two choices before us, we create :
- one big database,
- two hundred databases.
I do not have enough experience to answer. So I'll need to know what you
are advocating.
If the orientDB server can not contain any databases. Can we separate
databases? How?
3 / We have at least two hundred users who connect to each indexing XML
file. This represents 40,000 connections. The graph databases are in at
least 600GB.
What are the hardware and system recommendations on the computer that
hosts the server OrientDB: ram, disk-space, jvm, file system, OS?
Thank you for your help.
