record.save();
doc.field(BLOB, record);
properties.remove(BLOB);
}
This makes the bulk slower but not extremely slow.
Does this look ok to you is there a better method?
Grazie!

Hi guys,
I'd like to shed some light on this magic :-)
a RID is made of two numbers (a short and a long, at this stage, but the
first one will become a long too in next releases, it's in the radmap).
Say the RID is #xxx:yyy
xxx is the cluster ID, it identifies the cluster where the record is
Hi Antoine,
I suggest you to use the factory, it is much faster than manually acquiring
connections. If you are doing only read operations OrientGraphNoTx is ok,
just make sure that every actor has its own connection, the main constraint
you have here is that OrientDB connections are not thread
Hi Scott,
the term kept is not the one I'd use. If you think about data in an
Object Oriented way, it's correct to say that all the graph entities in
OrientDB are instances of V and E classes (but take into consideration that
you can use document classes that do not extend E or V). This is like

Hi Scott,
that kind of problem are you experiencing? Is it a parsing issue or is it
at query execution time? If you had a stacktrace it would help a lot.

Hi Scott,
the answer is yes, when using Graph API your elements have to be instances
of V and E.
If you work with may graph models, you have to create you own sub-classes
and sub-hierarchies under V and E and then query your own classes.
OrientDB v. 2.1 also supports multiple inheritance (a class
Hi Scott,
yes, exactly, you can define your own class hierarchies in OrientDB. There
is no need for a common superclass (like Object in Java), so two classes
can not have a common superclass at all.
V and E are just two conventional classes used for Graph representation

Hi Mohammad,
using a DB in embedded mode is slightly different than starting an embedded
server.
When you connect with plocal:/ url you just open a single DB from your
local VM, but you do not actually start a server, eg. you do not open
server ports (binary and HTTP, so other clients will not be

there is no such a function in OrientDB right now. If you are a Java
developer you can take a look at these classes

Hi Chaitanya,
RIDs are unique even in distributed environment. If the same record is
present in two different db nodes, then both copies of the record will have
the same RID of course.
OrientDB has a particular strategy to guarantee that RIDs are uniquely
assigned in distributed mode: the
ah, I suggest you to define an index (NOTUNIQUE) on the score property,
