Hi Giulia
I already created the vertex. Can't I import only edges?
There must be a way to instantiate existing vertices of a class...in my
case I imported activity_log separately so it is already there in
orientdb....
{
"config": {
"log": "debug"
},
"extractor" : {
"jdbc": { "driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost/dss",
"userName": "root",
"userPassword": "welcome101",
"query": "select * from activity_log" }
},
"transformers" : [
{ "vertex": { "class": "activity_log"} }
],
"loader" : {
"orientdb": {
"dbURL": "plocal:../databases/dss",
"dbAutoCreate": true,
"dbType": "graph"
}
}
}
I need to import 25 tables with multiple edges between them, It will
become tough to create one single json to import if I have to import edges
and vertices together. What do u suggest?
Thanks
Sam
