Hallo,
right now im trying to import freebase data dump into my orientdb using
java and:
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-graphdb</artifactId>
<version>1.6.5</version>
</dependency>
I use an transactional graph to create all my vertices and edges and i
always
gather 1000 operations before i commit all changes to the database.
After an hour of importing the data i got this error:
Exception in thread "main"
com.orientechnologies.orient.core.exception.ODatabaseException: Error on
