Hi 

We have started exploring OrientDB for building very lagre graphs ( 
cardinality of 1 million atleast) and most of the times we need
to use traverse command to cater our customers. Each node also comprises 
some properties ( 10 to 12 properties) .

 Would you please help us in addressing the following considerations to 
move forward;

    1.  We are planning to use a 8 to 16 GB RAM machine , and our data per 
day will be approximately 2GB, and we want to retain
         3 days of data into system. So is a single machine capable enough 
to scale with that data.

    2.  We get input data (event data)  from a messaging platform as and 
when event occurs, and we need to update the graph
         with these messages. Can orientDB cope up with such frequent 
updations ( may be 10 million messages a day). Do we need
         stop and start the server as and when we update the underlying 
graph, or is ot OK to update/modify (add a new vertex, edge)  the graph 
while the server is on.

   3. What kind of indexes/clusters can be created so that queries can be 
faster.

Regards
