Hi Curtis,
I don't know why you change from Person to Author, maybe this is the
problem?
However, use last release 0.9.2-SNAPSHOT. About the loader you can setup
more params. For example it's important for performance reason that you set
an index against Person.id. I've added also a log before and after
transformation. Try running the following:
{
"config": {
"verbose": true
},
"extractor" : {
"jdbc": { "driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost/test",
"userName": "root",
"userPassword": "",
"query": "select * from Author" }
},
"transformers" : [
{ log : { prefix: "BEFORE->" } },
{ "vertex": { "class": "Author"} },
{ log : { prefix: "AFTER->" } }
],
"loader" : {
"orientdb": {
dbURL: "plocal:D:\Eclipse LaTeX\DB - orientdb\databases\Test6",
dbUser: "admin",
dbPassword: "admin",
dbAutoDropIfExists: false,
dbAutoCreate: true,
tx: false,
wal: false,
batchCommit: 1000,
dbType: "graph",
indexes: [{class:"Person", fields:["id:string"],
type:"UNIQUE_HASH_INDEX" }]
}
}
}
